Do gatekeepers need a dedicated physical interface
I recently took control of a network that has several h323 vtc endpoints registered to a gatekeeper.
The 3700 router that is the gatekeeper has a physical interface that appears to only exist to be the IP address of the gatekeeper. The 3700 router has other physical interfaces such as the serial interface to the WAN plus the gateway interface for the LAN.
The 10/100 interface with the gatekeeper IP address has no other configuration besides the "ip address" command. It is also physically connected to the switch.
All the gatekeeper unique configs are in the gatekeeper config on the 3700.
Do I really need to dedicate a physical interface so be the gatekeeper? Can I usa loopback interface or use my gateway ip address?
Thank you.
We've redeployed out gatekeeper using /32 loop back interfaces. We have 2 routers each with a /32 loop back. Then we have 1 gatekeeper on each router configred in a cluster with each other. It works great. Now we can use that physical interface for something else and we have redundancy.
Thanks for the input.

The difference between IEEE802.1Q Native VLAN sub-interface and Physical interface?
Hello
I think the following topologies are supported for Cisco Routers
And the Physical interface also can be using as Native VLAN interface right?
Topology 1.
R1 Gi0.1 ------ IEEE802.1Q Tunneling L2SW ------ Gi0 R2
R1 - configuration
interface GigabitEthernet0.1
encapsulation dot1Q 1 native
ip address 10.0.0.1 255.255.255.0
Topology 2.
R1 Gi0 ------ IEEE802.1Q Tunneling L2SW ------ Gi0 R2
interface GigabitEthernet0
ip address 10.0.0.1 255.255.255.0
And is it ok to use the physical interface and sub-interface with dynamic routing such as EIGRP or OSPF etc?
R1 Gi 0 ---- Point to Multipoint EIGRP or OSPF ---- Gi0 R2 / R3
Gi 0.20--- Point to Point EIGRP or OSPF --- Gi0.10 R4 (same VLAN-ID)
R1 - configuration
interface GigabitEthernet0
ip address 10.0.0.1 255.255.255.0
interface GigabitEthernet8.20
encapsulation dot1Q 20
ip address 20.0.0.1 255.255.255.0
Any information is very appreciated. but if there is any CCO document please let me know.
Thank you very much and regards,
Masanobu HiyoshiHello,
The diagram is helpful.
If I am getting you correctly, you have three routers interconnected by a switch, and you want them to operate in a hub-and-spoke fashion even though the switch is capable of allowing direct communication between any of these routers.
Your first scenario is concerned with all three routers being in the same VLAN, and by using neighbor commands, you force these routers to establish targeted EIGRP adjacencies R1-R2 and R1-R3, with R1 being the hub.
Your second scenario is concerned with creating one VLAN per spoke, having subinterfaces for each spoke VLAN created on R1 as the router, and putting each spoke just in its own VLAN.
Your scenarios are not really concerned with the concept of native VLAN or the way it is configured, to be honest. Whether you use a native VLAN in either of your scenarios, or whether you configure the native VLAN on a subinterface or on the physical interface makes no difference. There is simply no difference to using or not using a native VLAN in any of your scenarios, and there is no difference to the native VLAN configuration being placed on a physical interface or a subinterface. It's as plain as that. Both your scenarios will work.
My personal opinion, though, is that forcing routers on a broadcast multi-access segment such as Ethernet to operate in a hub-and-spoke fashion is somewhat artificial. Why would you want to do this? Both scenarios have drawbacks: in the first scenario, you need to add a neighbor statement for each spoke to the hub, limiting the scalability. In the second scenario, you waste VLANs and IP subnets if there are many spokes. The primary question is, though: why would you want an Ethernet segment to operate as a hub-and-spoke network? Sure, these things are done but they are motivated by specific needs so I would like to know if you have any.
Even if you needed your network to operate in a hub-and-spoke mode, there are more efficient means of achieving that: Cisco switches support so-called protected ports that are prevented from talking to each other. By configuring the switch ports to spokes as protected, you will prevent the spokes from seeing each other. You would not need, then, to configure static neighbors in EIGRP, or to waste VLANs for individual spokes. What you would need to do would be deactivating the split horizon on R1's interface, and using the ip next-hop-self eigrp command on R1 to tweak the next hop information to point to R1 so that the spokes do not attempt to route packets to each other directly but rather route them over R1.
I do not believe I have seen any special CCO documents regarding the use of physical interfaces or subinterfaces for native VLAN or for your scenarios.

Multiple Public IP's on one physical interface for devices behind Router.
Hi guys, I am trying to find information on applying multiple IP addresses to a router
basically one for the Router itself and then some for the devices behind the router, Which i am sure I need to apply some 1 to 1 NATs. I just do not know if i need to specify all the IP addresses on the main interface.
Example being I have a router with WAN ip of xxx.xxx.xxx.xxx/25 , it only has 2 interface one for WAN one for LAN, i have a server I would like assigned its own public IP address. but still on the same LAN network.
Could someone help me out and point me in the right direction with a sample configI agree with the previous response that you need a static NAT to allow outside resources to initiate traffic to your server. You also will need NAT or PAT using the router interface address to allow the other hosts in your network to access outside.
You do not need to configure any other of the addresses on the router interface other than the primary IP that you assign to the router interface. As long as the other addresses are used for NAT/PAT they are configured in the nat statements and not on the physical interface.

How to make ASR9000 bridge domain forward traffic between sub interfaces of same physical interface?
Hi,
I regularly use bridge domains to connect sub interfaces on different vlans using this sort of configuration:
interface GigabitEthernet0/0/0/5.21 l2transport
description CUSTOMER A WAN
encapsulation dot1q 21
rewrite ingress tag pop 1 symmetric
interface GigabitEthernet0/0/0/10.3122 l2transport
description CUSTOMER A CORE
encapsulation dot1q 3122
rewrite ingress tag pop 1 symmetric
l2vpn
bridge group WANLINKS
bridge-domain CUSTOMERA
interface GigabitEthernet0/0/0/5.21
interface GigabitEthernet0/0/0/10.3122
When I try to use the same method to bridge two sub interfaces on the same physical interface so as to create a L2 VPN no data flows:
interface GigabitEthernet0/0/0/5.21 l2transport
description CUSTOMER A WAN
encapsulation dot1q 21
rewrite ingress tag pop 1 symmetric
interface GigabitEthernet0/0/0/5.22 l2transport
description CUSTOMER A WAN2
encapsulation dot1q 22
rewrite ingress tag pop 1 symmetric
l2vpn
bridge group WANLINKS
bridge-domain CUSTOMERA
interface GigabitEthernet0/0/0/5.21
interface GigabitEthernet0/0/0/5.22
If I add a BVI interface to the bridge domain then the CE devices at the remote end of the WAN interface can both ping the BVI IP but they remain unable to ping each other.
Is this because tag rewrites are not happening since packets don't leave the physical interface?
How can I work around this and establish a L2 connection between the two subinterfaces?
Thank youa vlan is usually the equivalent of an l3 subnet, so linking 2 vlans together in the same bridge domain, likely needs to come with some sort of routing (eg a BVI interface).
If these 2 vlans are still in the same subnet, then there is still arp going on, from one host to the other that traverses the bD.
you will need to verify the state of the AC, the forwarding in the BD and see if something gets dropped somewhere and follow the generic packet troubleshooting guides (see support forums for that also).
that might give a hint to what the precise issue in your forwarding is.

DMVPN using loopback interface vs. physical interface
In a DMVPN,what´s the difference between using a loopback interface as a tunnel source instead of a physical interface?
It will work for a static one to one nat. PAT doesnt play well with GRE because ports dont exist in GRE (not sure if NAT traversal can help here like it does with ISAKMP - it works on spokes) You also need to make sure that the loopback is set to work with the crypto profile. Joe is right, the address it terminates on is best to be Public address space that you own, that is multihomed - if this is a hub.

Network = 2 subnet on 1 physical interface on 1 VLAN
Hello,
For migration purpose I will need to configure a physical interface to be at the same time on two different subnet on only 1 physical interface.
On router it is called secondary IP but I don't know if sun is able to do that. I have no routing trouble as Sun servers are just talking in local.
example:
10.0.0.1---------
| ----------> same physical (if) and logical network (VLAN)
192.168.0.2----
Any clue would be helpfull
Thanks !Ok I have done test and I know that it is possible but I have 2 bugs :
-when restarting my server I get an error and must restart manually my interfaces ( exit status 96 ...) and manually add my default route which was not taken...
- I must specify my subnet in the hostname.ce0 for IP addresses that are in a "sub-network"
here is my config :
# cat /etc/hostname.ce0
toto + netmask 255.255.252.0 + up
addif test + netmask + up
# cat /etc/hosts
10.170.225.205 toto loghost hostname
127.0.0.1 localhost loopback

Policy-map on tunnel or physical interface?
Hi all,
I have a 3800 headend router which has a number of ipsec tunnels to remote office sites. Our current QoS design applies a policy-map to each tunnel interface to prioritise and shape outbound traffic.
My question is how does the physical egress interface queue and transmit traffic from tunnel interfaces with this design? For example, if a mixture of large data packets and voice packets from different tunnel interfaces hit the physical interface around the same time what will happen to the voice packets?
Furthermore, would it be a better to apply the policy-map to the physical interface instead of the tunnel interfaces? What advantages if any would this bring?
Many thanks.If you're shaping each tunnel to the outbound physical bandwidth, yes it would be better to just have the policy, without any shaping, on the physical interface. Again, you'll will either need to depend on a copied ToS value in the outbound packet or use qos pre-classify. (A single physical policy would be much like your QUEUE_DATA if using qos pre-classify.)
e.g.
!assumes qos-preclassify
interface Ethernet0
service-policy output QUEUE_DATA
What I thought you might be doing, and you could also do, was shape each tunnel to the far side's ingress bandwidth. This would require a distinct policy, if the shaper values change, for every tunnel interface, or a policy on the physical interface that has a class per tunnel (matches against tunnel destination address).
e.g.
!assume local outbound interface not oversubscribed
policy-map NESTED_QOS_512K
class class-default
shape average 512000
service-policy QUEUE_DATA
policy-map NESTED_QOS_768K
class class-default
shape average 768000
service-policy QUEUE_DATA
policy-map NESTED_QOS_1500K
class class-default
shape average 1500000
service-policy QUEUE_DATA
interface Tunnel1
service-policy output NESTED_QOS_786K
interface Tunnel2
service-policy output NESTED_QOS_512K
interface Tunnel3
service-policy output NESTED_QOS_1500K
interface Tunnel4
service-policy output NESTED_QOS_512K
e.g.
!assume local outbound interface not oversubscribed
class-map match-all Tunnel1
match group (ACL that matches tunnel1 destination address)
class-map match-all Tunnel2
match group (ACL that matches tunnel2 destination address)
policy-map outbound_tunnels
class Tunnel1
shape average 768000
service-policy output QUEUE_DATA
class Tunnel2
shape average 512000
service-policy output QUEUE_DATA
Interface Ethernet 0
service-policy outbound outbound_tunnels
If all the far side bandwidths exceed your local outbound physical bandwidth, then you should have both tunnel policies, that shape each tunnel, and a physical interface policy.
e.g.
!assume local outbound interface is oversubscribed
policy-map NESTED_QOS_512K
class class-default
shape average 512000
service-policy QUEUE_DATA
policy-map NESTED_QOS_768K
class class-default
shape average 768000
service-policy QUEUE_DATA
policy-map NESTED_QOS_1500K
class class-default
shape average 1500000
service-policy QUEUE_DATA
interface Tunnel1
service-policy output NESTED_QOS_786K
interface Tunnel2
service-policy output NESTED_QOS_512K
interface Tunnel3
service-policy output NESTED_QOS_1500K

Virtual interface or physical interface
Hi All,
Need your help select IPSce config in following environment
We are working in Joint venture. Two different companies are working under one banner. But one company's computers requires services from other company's server.
We are thinking to make site to site connection along with IPSec. Both sites have static public IP's.
Configuring Virtual Tunnel interface OR
Configuring Physical Interface OR
GRE Point to PointHi Omer,
I would prefer VTI on GRE over IPSec . Although IPsec provides a secure method for tunneling data across an IP network, it has limitations. IPsec does not support IP broadcast or IP multicast, preventing the use of protocols that rely on these features, such as routing protocols. IPsec also does not support the use of multiprotocol traffic.
GRE is a protocol that can be used to “carry” other passenger protocols, such as IP broadcast or IP multicast, as well as non-IP protocols.
Vitual Tunnel Interfaces you can set them up with a profile that uses IPsec for transport and so the interface tu0 is treated like a usual IP interface that can also handle routing protocols.
However, different tunnel mode can apply different application. Here are some considerations for IPSec VTI. The IPsec VTI is limited to IP unicast and multicast traffic only, as opposed to GRE tunnels, which have a wider application for IPsec implementation. Thus, for some non-IP traffic, we still need IPSec over GRE.
Header related overhead is about same, However VTI is less CPU intensive. Well also matter what platfrom is part of solution.

MPLS Customer router physical interface
My provider wants to sell me MPLS services but I can't seem to get a straight answer regarding what the physical interface on my customer router needs to be. Some personnel tell me it will be a normal ethernet connection, other say it'll be a DS3 or T1 connection depending on the speed.
Please give me some advice on what to expect regarding an MPLS circuit? Or point me to some good documentation to maybe I can communicate better with the service provider.
Thank you.Hi Tod
Few points from my side for your query
Access Link should be considered based on whether we are going for MPLS L3 VPN or MPLS L2 VPN Soilution
MPLS L3 VPN from my understanding is independent of Access Media but the Access Media will definitely put different hardware requirements for your Customer Edge Router
The Access Link Type and Bandwidth would vary depending upon the BW requirements for the network. The T1/T3 or a Subrate T3 Access Links would be a choice when we have BW requirements in that range(<45 Megs)
Using FE as an Acces link would require SP to provide Colocation Services or rather go for spanning a Fiber out from their Colo and deploying Optical Mux at Customer Premises and again suitable for BW requirements more than 45 Megs
MPLS L2 VPN
Ethernet is the choice for taking MPLS L2 VPN Services to connect your different branches in a point-to-multipoint fashion using VPLS at SP end.
You can go through the Cisco Doc - "Layer 3 MPLS VPN Enterprise Consumer Guide" which should help you gain more insight for choosing the PE-CE Routing Protocol and other points to consider for an MPLS L3 VPN Service.
Thats from my understanding. Hope you will get more good advises on this.

DO i need some extra hardware interface for receving both Audio and video
hi i m doing e-learning project. i have to capture video from webcam and voice from headphone and send to client.
but my code is working fine for either one at a time.
DO i need some extra hardware interface for receving both Audio and video. im using code AVTransmit and AVReceive found from this site only
After running TX
i give Dsound:// & vfw://0 in Media Locater only sound is received and no vedio
and when i give vfw://0 in Media Locater only live video is transmited.
im using JMF1.1.2e.
if any one know the method to run or cause of it plz reply me soon. i will be very thankfull

How to Add a Physical Interface After Installation in Solaris 10
How to Add a Physical Interface After Installation in Solaris 10
Hi Java Specialist,
I am trying to setup a network interface with the following steps on a new fresh Solaris 10 installation using the instruction titled How to Add a Physical Interface After Installation in Solaris 10 3/05 ONLY from http://docs.oracle.com/cd/E19253-01/816-4554/esxhb/index.html:
1. # ifconfig lo0 plumb up
2. # ifconfig lo0 10.56.8.101 netmask 255.255.240.0. This was the working Windows DHCP environment prior to installing Solaris
10 on top of it.
3. # Added saturn to /etc/hostname.lo0.
4. # Added 10.56.8.101 to /etc/inet/hosts
5. # Added 10.56.0.0 255.255.240.0 to /etc/inet/netmasks
6.# reboot
However, the following errors kept recurring:
svcs –xv …. unable to qualify my own domain name,
failed with exit status 69.
Any idea on what other steps have I missed? I was hoping to only do step 3 – 6 for the change to apply permanently.
Many thanks,
JackHi Java Specialist,... in a Solaris forum?
1. # ifconfig lo0 plumb upThe loopback connection (your lo0)is NOT a physical interface. There are no hardware components for it. Nor can I think of any reason why it should ever be anything other than the default 127.0.0.1
Use your favorite Internet search site (such as Google, Bing, Yahoo) to learn more about it.
2. # ifconfig lo0 10.56.8.101 netmask 255.255.240.0. This was the working Windows DHCP environment ...I have no idea how a nonexistent software construct gets a DHCP address in a MS Operating System, unless you are confusing this with the "Microsoft Loopback Adapter" which is an utterly different concept. Again, go see what Google tells you.

... completely unrelated to configuring an IP...
unable to qualify my own domain nameAgain, search the Internet or even search these forums with that string of words.

Can anybody help?
I am considering buying a new MAC laptop to run LOGIC for composition and band live/recording, but which one is best as I do not want to spend too much money?
Does it have a line in and how do you monitor sound?
Will I need adaptors and an interface?
Also, I am guessing as Logic only runs on MAC surely then they would not the best spec to recommend to run it?
I see all the upgrades as additional memory or a faster process?
Is a retina screen necessary, and why flash based storage against a 1TB hard drive, and a i5 instead of an i7
The main reason for this purchase is to play live and use backing tracks and record found sounds and make creative songs.
I hope you can provide some valuable feedback, as I am a longtime MAC user and see upgrades and changes happen regularly but the most important thing is the songs not the equipment.
I have £500 already and willing to add another 500 to 700 pounds, then software extra.Can anybody help?

1 policy-map for more than 1 physical interface
Hi,
the situation I want to achieve is, that 2 physical interfaces (here 2 TP GigbitEthernet Ports of a 3750) are limited together from one 'service-policy'/'policy-map'.
In the example below I have 2 Ports on one switch and the traffic coming in on both ports in total (traffic port #1 + traffic port #2) should be limited to the 'policy-map 5MBits'.
Right now I have configured a 3750 with:
class-map match-all EveryMAC
match access-group name everythingL2
policy-map 5MBits
class EveryMAC
police 5000000 32768 exceed-action drop
policy-map TEST
class EveryMAC
set dscp default
mac access-list extended everythingL2
permit any any
interface GigabitEthernet1/0/1
description port #1
switchport access vlan 123
switchport mode access
speed 10
duplex auto
interface GigabitEthernet1/0/2
description port #2
switchport access vlan 123
switchport mode access
speed 10
duplex auto
interface Vlan123
service-policy input TEST
And at the 'other side' a 2950 works with the following config:
class-map match-all EveryMAC
match access-group name everythingL2
policy-map 5MBits
class EveryMAC
police 5000000 32768 exceed-action drop
mac access-list extended everythingL2
permit any any
interface FastEthernet0/1
description port #A
switchport access vlan 123
switchport mode access
speed 10
duplex auto
As far as I can see this seems to work. But it would be nice if someone can confirm this or provide an other suggestion.
thanks in advance
MarkOnly thing i can think of is instead of using a MAC ACL , u cud jus use the default class
Policy Map Test
class class-default
police 56000 8000 exceed-action drop
Class Map match-any class-default (id 0)
Match any
You would be saving a MAC-ACL ;-). -
Can I assume that Windows will be able to handle my physical interface device if I follow the "Device Class Definition for Physical Interface Devices" specification while writing the firmware?
I'm trying to develop a device which handles rumble output from applications such as games. Applications would include e.g. racing games or simulators. I'm hesitant to just clone Xbox 360 Gamepad or Sidewinder USB reports. I'd like to correctly declare my
device as something on its own while still making use of already implemented OS-specific drivers. The purpose of the mentioned specification is exactly that as far as I can tell. I wasn't able to find concrete information about its level of support though.
The "USB device class drivers included in Windows" page (sorry I'm not allowed to post links yet..) seems to link to WinUSB which I'm not sure what to do with.Thanks for your response. Well if everything was implemented at that time and it's still available it should be fine since the specification document's last version is dated 1999. I was just hoping there would be any form of documentation whether it's
supported and by which degree so I don't go through the trouble of figuring out how the firmware should be written according to the specification just to find out there is no OS driver implementation for it which would render my work more or less useless.
So I suppose I'm forced to go the trial and error path? -

Sorry but this has nothing to do with Windows Server Security, which is the
purpose of this forum. You're going to need to ask this question wherever
"hiphop for PHP" is supported and that won't be a Microsoft support forum.
