CE dial-in to PE. What routing protocol I should use ?
Hi,
Situation - CE connected to PE via some ethernet interface (primary) and ISDN dial-up as backup, so I need to use some dynamic routing protocol to distribute customers networks to other sites. Now I'm looking towards extended (triggered) RIP, but maybe there are better choices?
As I know, only triggereg RIP and OSPF supports 'on-demand' circuits, but OSPF isn't recommended as CE-PE protocol because it has no VRF awareness and we would have to run separate OSPF process for every VRF what isn't nice. This makes RIP only choice? Or there are another possibilities, maybe BGP ?
Hi,
over all there is static, RIPv2, EIGRP, OSPF, ISIS and BGP for PE-CE.
Well floating static alone seems no possibility in your case.
RIP and EIGRP have some issues when running on redundant links into the VPN (possibility of routing loops), which would be the case with backup active and primary coming back. Depending on the exact topology there might or might not be a workaround.
OSPF has to be run as separate processes. Might be tough on PE resources, depending on your exact setup details. Other than that it does the job.
eBGP with ebgp-multihop and static routes is an option. So eBGP doesn´t go down, just is directed over backup link in case primary is down.
Pick your poison! :-)

What kind software we should use under VISTA to creat new partition.
hi,there. i've use the boot camp to install the window vista in my macbook. but the boot camp only creat one partition for it. therefore all the partition i have under vista is C partiton. i want to divide that C partiton into 2 or more partitons, but i just wonder will that gonna destroy the boot information for Mac OS? what kind software i should use to avoid that problem? thanks.
Don't know. Never used it. You should probably post your question in the Boot Camp discussions

We currently use IPsec for our VPN setup. This includes a single core and approximately 75 (and growing) hubs. I'm currently labbing a DMVPN environment to run some tests as part of a planned move.
I know this question has been covered, but wanted to get some fresh perspective. What routing protocols are you using for DMVPN and what are some of the issues you have faced?Adam,
Most of the setups world wide will use EIGRP or BGP, very few specific cases use RIP passive, some OSPF or static routes.
For scaling and most internet-based setups we do recommend using BGP. It's well known, manageable, allowing load balancing and with a few tweaks perfect for large routing table and decent recovery times.

What bluetooth protocol does the iPod Touch use with a keyboard?
Hi...
Say, does anyone know what bluetooth protocol apple is using for their bluetooth keyboards for the iPhone and iPod Touch? It is probably HID, but the people at RIM (i.e. BlackBerry) use SPP. So I would think many 3rd party keyboards use SPP (Serial Port Protocol). But, then, there are many posts about "I wish Apple would support SPP" because people want to build apps that interface with external HW that only supports SPP.
What I want to do? (you ask)
I've one of these nice / expensive Think-out-side portable folding keyboards (good). That only has a serial interface (bad). There are many bluetooth "dongles" out there with serial ports (good). But they only support SPP or Serial Port Protocol (bad? maybe? depends).
See, I know RIM (BlackBerry) people support SPP on their devices. But I haven't heard (found) word one about what the iPod Touch supports. I would hate to spend $80 on one of these dongles and find out it doesn't work.
So, what does the iPod Touch use when talking to the bluetooth keyboard?
-thanksFrom page 37 of iOS 4.1 Touch Users Guide:
Using an Apple Wireless Keyboard
For ease of typing, you can use an Apple Wireless Keyboard (available separately;
iPod touch 3rd generation or later).

What JDBC drive I can use in Tomcat
Hi all. I'm trying to shift my web application(JSP and JavaBeans only) from JRUN to Tomcat 4.1. I used sun JDBC driver or JRUN's own JDBC driver to connect to Microsoft SQL Server 2000 and both worked. Now since I'm setting up the same thing in Tomcat, I have totally no idea about what JDBC driver I should use and how to do it. I'm wondering whether Tomcat itself provides any JDBC driver? Or if not, how to make it work with Sun's driver? Or some more, is there any free driver available which is workable?
Thanks a lot for any help!As you said in production envio you have set up
up another server which will be the primary server
for the application.Though, your application works
well in Tomcat, it 's not complete solution in
production envio.That depends on what the "production" system is intended to do, how many users it serves, what are the security concerns, etc.
A low usage, internal system can easily be run with just Tomcat. -
Dynamic Routing Protocols - what do I really need to know?
Ok, ridiculously broad question I know but....what I'm trying to figure out is, let's say I'm in a large coproration and I have multiple field sites in different areas of the country so the network setup may be somewhat complex but when it comes to setting up the dynamic routing...is it as simple as let's say, configuring a router to use BGP for whatever portion you designate then just letting it be? is it somewhat challenging to initally configure dynamic routing protocols (i.e. how often have you found yourselves worrying about admin distance, areas (I don't even know what an "area" is yet either so if anyone could explain that I would appreciate it), etc..
So in short, are dynamic routing protocols "Set it and forget it" or do they require a ton of planning to setup? I'm familliar with the differences between them (i.e. OSPF, RIP, EIGRP,etc..) and the differences in link state and distance vector but I just wanted to ask about the setup of the protocols themselves.
Thanks!!You can exchange routes between protocols with redistribution.
The problem with the question is, as you say, it is too broad to really answer properly.
All routing protocols have different considerations so what you might do for EIGRP you may not do with OSPF and BGP is different altogether.
As a general answer if you are enabling it across a WAN all take a certain amout of planning and design and they all rely heavily on what you have done with your IP addressing in terms of summarisation etc.
The actual configurations to get a basic setup running are relatively simple, certainly for IGPs, but as your network grows you may find the configurations becoming more complex
BGP is a very different in that there are many different commands you can use to influence the path traffic takes but even here to setup a very basic BGP peering only requires a few commands.
But no routing protocol in a large environment should just be configured with no thought as to how it is going to work, traffic paths, number of routes etc.
You can do it but you may well find as your network grows you will end up having to revisit the whole thing because it is not working as you intended.
Like I say it's too large a question to really answer because each routing protocol is different and may or may not meet the requirements of the network.
If there are more specific questions then please feel free to ask.

Wireless ad hoc routing protocols
I have an application that uses wireless ad hoc routing protocols (node-to-node communication). Has anyone developed any application that implements wireless ad hoc networking protocols, such as route discovery, route maintenance etc. using LabView? If so, I'd appreciate if you could provide more insight on your application.
Thank you in advance.I've done something like that in the past, but LV was not the interface to the network.
Basically, LV was used to control parameters within an embedded system (running Linux-Embedded) and sending commands over serial and / or Ethernet ports. The system was comprised of multiple boards, each running an OS with 3 layers of communication, some of which were serial, most over Ethernet.
However, the firmware took care of discovering and setting up the network. LV simply quieried the system to find out what it had to deal with (how many boards, what type, etc), then it would quiery the application to find out if the expected networks were esblished and to allow permissions over the network.
Are you trying to achieve something similar or are you trying to implement (setup) the network directly using LV?

Routing Protocol recommendation for MPLS Network
I am in the process of building a 14 site MPLS network for voice and data traffic. The vendor installing the network has configured RIPv2 as the routing protocol. I am considering switching this over to EIGRP. Can anyone explain to me why this would be better or should I just stay with RIP.
ThanksHi Chip,
Its not very clear whether you are implementing a MPLS network or implementing a Network over MPLS for an end user with 14 sites.
1) If MPLS network then other IGP variants than OSPF and ISIS best avoided. Now if the choice is between ISIS and OSPF then my personal recommendation would be OSPF. And this decision is purely driven by Operational Considerations rather than any technical advantages. Since at the end of the day what matters is how easy it is to implement add delete or troubleshoot the network.
2)If for End User then it would not be right to recommend EIGRP or RIP or OSPF without knowing the current size & topology of each of these 14 sites, as well as the desired expansion plans. But if these 14 sites are the only sites and are all standalone branch sites connecting over MPLS VPN then RIP,EIGRP or OSPF can be implemented as per your and customer comfort.

Hi all,
i have to implement a network customer over a vpls provider ( 60 site L2 any to any).
which protocol for this design ? eigrp, ospf or bgp with advantage or inconvenient?
thanks,If this is to be a layer 2 network for 60 sites with any to any connectivity then you can choose which ever routing protocol you wish since the provider will not be participating in the routing protocol. BGP would be at the bottom of my list for this for several reasons, one of which is that BGP does not do dynamic neighbor discovery and I would not want to manually configure 59 neighbors on each of 60 routers.
Either OSPF or EIGRP could be good choices. If we knew more about this network it might be possible to favor one or the other. For OSPF it seems likely that you would have a single area and some people might be concerned about 60 peers in a single area. But I think it could be appealing that most routers would go through full adjacency with only two peers where with EIGRP each router would negotiate neighbor relationship with 59 neighbors. Another consideration might be what the topology of the sites is like. If each site has several subnets and if the subnets fall into summarizable ranges then EIGRP might be preferred since it enables summarization from each of the routers which reduces the complexity of the routing table on each neighbor.

IPSEC tunnel and Routing protocols Support
Hi Everyone,
I read IPSEC does not support Routing Protocols with Site to Site VPN as they both are Layer4.
Does it mean that If Site A has to reach Site B over WAN link we should use Static IP on Site A and Site B Router?
In my home Lab i config Site to Site IPSES VPN and they are working fine using OSPF does this mean that IPSEC supports Routing Protocol?
IF someone can explain me this please?

crypto ipsec transform-set aes esp-aes 256 esp-sha-hmac
mode transport
crypto ipsec profile tp
set transform-set aes
int tu1
ip address 255.255.255.252
tunnel source
tunnel destination
tunne protection ipsec profile tp
We have configured mode transport because we encrypt GRE + what ever we encapsule in GRE [ eg OSPF - telnet - http ]
Pros:
We can as well transport IPV6 or CDP
Cons:
4 bytes of overhead due to GRE
2- IP over IPSEC
crypto ipsec transform-set aes esp-aes 256 esp-sha-hmac
mode tunnel
crypto ipsec profile tp
set transform-set aes
int tu1
ip address 255.255.255.252
tunnel source
tunnel destination
tunnel mode ipsec ipv4
tunne protection ipsec profile tp
This config is in fact closer from a crypto map [ from encapsulation standpoint]. The transform-set then NEED to be in tunnel-mode
Pro:
4 bytes overhead less than GRE over IPSEC
Cons:
Cannot transport CDP or MPLS or IPV6. Very limiting IMHO

When using these we advertise the network according to what ip the interfaces are on, does this just include the interface in the routing protocol to be part of the process ?
Well, honestly depending on the routing protocol you are going to use. EIGRP and OSPF for example depend on which interface will form neighor relation ship and depending on what network is on the interface it will be advertised. However, BGP does not depend on the interface and you use the network command to advertise the subnet you want.
Therefore, when you issue the network command under the EIGRP and OSPF it means you are saying that these interfaces can send and receive hello packets and form adjacency or neighbor relation ships. However, the advertised subnet will be that of the interface. For example, if you issue the command network 10.20.30.1 0.0.0.0 this means only this interface will form neighbor relationship however the advertised subnet would be 10.20.30.0/24 in case this is the interface subnet.
