DMVPN over two sub-interfaces

Hello,
I need to configure a DMVPN spoke to join an existing DMVPN.
My problem is that the interface that connects to the Internet has a double feed. Basically fa0/0 is configured with two sub-interfaces fa0/0.X and fa0/0.Y.
My doubt is if I can put the tunnel source as fa0/0 simply and it will apply it on both? I know it is a fairly simple question but since I am about to apply it on a live system I really wanted to be sure.
Thanks,
Paulo

Because ip addresses are assigned to sub-interfaces I think tunnel source should be pointing to sub-interfaces.

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 you

a 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.

HSRP using sub-interfaces,

I'm planning a design that will need two 2950s to support 4 vlans. Non-local traffic will be routed out via one of two HSRP routers (one pair of vlans using router 1 as a primary, the other pair using router 2).
I've dug around the cisco documentation but can't find an answer to the following...
Does HSRP run ok over sub-interfaces?
For example, VLAN 1 default gateway will be HSRP (virtual) router's f0/0.1 x.x.x.x, VLAN 2 default gateway will be HSRP router's f0/0.2 x.x.x.x, etc.
Any ideas?

Hi Dwatson,
YES, HSRP supports on sub-interfaces also & there wouldn't be any problems.YES the default gateway would be the HSRP standby ip address specified on the sub-interface for the vlans.
eg.
Router A
interface FastEthernet0/0.1
description ***ABC***
encapsulation dot1Q 1
ip address 172.16.1.2 255.255.0.0
standby 1 ip 172.16.1.1
standby 1 timers 5 15
standby 1 priority 108
standby 1 preempt
Router B
interface FastEthernet0/0.1
description ***ABC***
encapsulation dot1Q 1
ip address 172.16.1.3 255.255.0.0
standby 1 ip 172.16.1.1
standby 1 timers 5 15
standby 1 priority 109
standby 1 preempt
Note donot give any ip address on the fastethernet interface.
interface fasthethernet 0/0
no ip address
hope this helps.

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,

Hello,
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.
Best regards,
Peter

Sub-interfaces on n5k

Hi, I am trying to connect N5k (layer-3) and ASA, there is a requirement where some of the security-sensitive vlans have their layer-3 on the ASA and for those vlans who are less-sensitive have their svis on the N5k. I am doing a POC in my lab gear first. The n5k and the ASA are connected by 1 physical link having sub-interfaces on both the ends. There is a sub-int with vlan 10 (10.1.1.0/30) on both sides and the ASA injects a default-route to the N5k over this. so in case a non-secure vlan needs to talks to a secure-vlan it goes through via this path. My issue is that, if i create a sub-intf on the ASA, give it a vlan tag of 20, and on my N5k i add a port in that same vlan, i cannot ping my GW (ASA) from the laptop. I have also created a similar sub-int on the N5k side as well with tag 20, BUT still does not work.
attached visio.
Any clues??
Thnx

Include multiple sub-interfaces in Cisco ASA for VPN tunnel

I am trying to create a VPN tunnel between two Cisco ASAs where one ASA has multiple sub-interfaces.
Say, In Cisco ASA 5550(in datacentre), I created multiple subinterfaces with VLAN ID as below:
Inside, int0/1 : 10.1.1.0/24
DMZ, int0/1.100: 10.1.100.0/24 (VLAN 100)
Production, int 0/1.101 : 10.1.101.0/24 (VLAN 101)
Management, int 0/1.102: 10.1.102.0/24 (VLAN 102)
And another Cisco ASA 5505 is only configured with 1 x inside interface Inside, int 0/1: 192.168.1.0/24
So far, I have only been able to provide outside access to one of the sub-interfaces as NAT rule on inside interface didn't work for VLANs. Hence had to issue Global NAT rule to be applied on Production subinterface so that production VLAN can have outside access. I have managed to establish VPN tunnel between two ASAs on Production sub-interface only, Source interface = Production subinterface
Additional settings:
Have ACL to allow all sub interfaces to access outsite ( lower security level)
NAT rules is configured on Production subinterface with Source NAT Type as Dynamic PAT; when this was configured with source interface as inside, PCs behind various VLAN coun't access internet.
I want to establish a site-to-site VPN tunnel with multiple sub-interfaces of Cisco ASA 5550 to Cisco ASA 5505. Would you please suggest what I am missing in my configuration? I need to be able to access multiple VLANs of datacentre from remote site.

Traffic Shaping on Sub-interfaces

Hi all,
On my network i am trying to give preference to certain traffic type A over another traffice type B over a VSAT link.
the VSAT link is about 64Kbps/64Kbps and this link is connected to a router subinterface.
I initially thought of CBWFQ to reserve bandwidth for the differenct traffic types but there are restrictions to using CBWFQ on Sub interfaces.
Hence I tot of the option of shaping the less preffered traffic to a less than half the bandwidth say 24K will be a good idea however i worry that the contents of the shaping queue will constitute both the preffered traffic and the less preffered traffic hence introducing more delay to the more preffered traffic. which is not required.
Any other better ways to achieve this?

You can use hierarchical qos:

DMZ Sub interfaces into sub interface

Hi,
We have ASA FW 5010 in our organization and we have 4 DMZ's under the DMZ interface on ASA and all DMZ's are created on sub interfaces and assigned different VLANS on each DMZ's like
DMZ-1 = 172.20.1.x - VLAN 1000
DMZ-2 = 172.20.2.x - VLAN 1200
DMZ-3 = 172.20.3.x - VLAN 1300
DMZ-4 = 172.20.4.x - VLAN 1400
My question is:
Can we break sub interface (DMZ-4) into again another sub interface and assign another IP address like
DMZ-4 = 172.20.4.x
---------= 172.20.5.x
Means one VLAN has two IP addresses for gateway.
One thing more how many times we can break one interface into subinterfaces.
I hope my question is enough for understanding.
Regards,
Saeed

> Can we break this feature on catalyst switches 2960 or 3560?
You just want to have two IP-networks in one VLAN? If yes, that is possible on Routers and Switches with secondary IP-addresses. But the ASA doesn't support that.

Policy maps on port-channel sub-interfaces

We're trying to implement an enterprise QoS policy and I'm wondering how we can apply our QoS policy maps to several different sub-interfaces on a port-channel. In our case, we have both LAN and WAN connections that connect as VLANs on a switch and terminate as sub-interfaces on a port-channel that combines two Gigabit Ethernet interfaces on our router. The LAN connection will need to have a ingress service-policy to classify traffic as it comes from a customer LAN, and the WAN connections will have to have an egress service-policy to place the traffic classes into LLQ and CBWFQ queues as it leaves the router. Could I put both the ingress and egress service-policies on the physical router interface, or should I put them on the port-channel interface? Or should I apply them to the individual sub-interfaces? For example, I could put the ingress classification service-policy on the LAN sub-interface connection.
Any thoughts or insight would be helpful. Thanks.

I can't put it as input because :
gw-a(config-subif)#service-policy input policy_upload
Traffic Shaping feature not supported in input policy.
Here's a show during a bandwidth test. You can see the offered rate is properly measured and is _way_ above the target shape rate.

Disable BFD in multiple Router Sub interfaces that participates in OSPF

Hi team,
Please help me on this. Here is the scenario:
We are on an enterprise set up and running on 100+ routers.
We have 200 to 300+ sub interfaces for virtual circuits
Our protocol is OSPF over MPLS
One of our provider in LA encountered link flaps on SONET causing our LA router that is directly connected to that link to recalculate multiple times.
Recalculation of OSPF routes caused disconnection of users in LA VM's.
We were advised by our provider in LA to disable BFD so minor link flaps will no affect recalculation of routes.
We are now tasked by our design team to Disable BFD in multiple Router Sub interfaces that participates in OSPF.
My questions are:
What is the implication in disabling all BFD in routers' interface and sub interface?
Will this improve recalculation of OSPF routes in cause of link flaps or it will totally ignore the link flaps?
Will the routers only recognize a "full down" status of the interface?
How can we Disable BFD in multiple Router Sub interfaces that participates in OSPF in a faster way? Or do we have to do this one by one?
Please advise before we present this to the CAB and implementation. Thank you.

My questions are:
What is the implication in disabling all BFD in routers' interface and sub interface?
Answer: the implication would be eliminating sub-second millisecond convergence.
BFD detect failure at the link layer very fast , once detected it informs the upper layer protocol about the failure causing it to converge immediately.
Will this improve recalculation of OSPF routes in cause of link flaps or it will totally ignore the link flaps?
Answer: if your Provider experiencing intermittent flaps, then yes it will be advisable to turn BFD off. this however doesn't totally ignore the link flaps, once the upper protocol detect the failure based on the dead interval parameter on OSPF, it will recalculate OSPF routes again. Keep in mind, if you have redundant or more links to your provider , then I wouldn't recommend disabling BFD , as it should improve Convergence and you shouldn't notice the failure.
Will the routers only recognize a "full down" status of the interface?
Answer: disabling BFD allows the router recognize a full down status once the upper protocol dead interval occurs or full down status of interface. which ever occurs the earliest.
How can we Disable BFD in multiple Router Sub interfaces that participates in OSPF in a faster way? Or do we have to do this one by one?
You can disable it one by one. or if you have configuration management software, it allows you to do it for all nodes at a time. but this depends if you have it or not.
Please consider not to disable BFD if you have multiple OSPF links towards your provider from any branch, as it shouldn't impact your VMs, it should rather improve Convergence at milliseconds which is absolutely not noticeable.

IPSec tunnel on sub-interface on ASA 5510

Hello All,
I working on a security solution using ASA firewall and need some technical advice on ASA. Is it possible to setup a IPSec tunnels on each subinterface of a physical interface on ASA 5510?
I would be greatul if someone please reply post this with some details.
Regards,
Muds

Hi Jennifer,
Thanks very much for your reply. I understand where you coming from, but the reason of using sub-interfaces is that, we have only one physical interface on the firewall connected to the MPLS cloud, and we need to setup a seperate IPSec tunnels for each client for security and integrity. In the current scenario, I have static peers and we can easily setup a static route to peer address.
Many thanks for your assistance, please feel free to to advise if you have any other suggestion.

Asa 5505 sub interface plus ports

I have never used 5505 I gave used higher firewalls and all of them can do sub interfaces normally we make sub interfaces and vlans are assigned to them I m trying to config 5505 can someone tell me how I can create sub interfaces ? As I saw few config and it seems that you config vlans like switch ??? Secondly all interfaces have to b part of vlan ? Ie outside which is g0/0 ....can I config it as normall routed port ?

The 5505 is configured nearly the same a a L3-switch. You configure the Vlan-interfaces and assign these to your switch-ports. The switch ports can be configured as access- or as trunk-ports (if you have a SecPlus license).
You find more on this topic on the Config-Guide:
