BGP with Quagga and static routing suggestions


Dear All,

We need to implement BGP with 10 peers. Out of them 3 have dropped fiber link to our premises and rest are dropped from a single fiber link from IX.

We are thinking to use Quagga for BGP.

Also there is another connection which doesnt have BGP peering but static routing.For example: 10.2.1.0/24 network is being routed using static routing of Linux.

I have few questions for this scenario... Looking forward for your help:

1.) Can we implement all these in same machine? We are using CentOS 5.5.

2.) As number of available NIC cards is limited to 3. Can we use alias (eth0:1...) for BGP? Is that a good idea.

3.) Shall we use iproute2 for static routing?

4.) We are using only bgpd daemon (not zebra)... I tried implementing the BGP using Quagga... BGP network is announced and I can see neighbors but the routing is not shown when I type route -N. Only sttaic routings are shown.



Thanks in advance

I see no reason why not.

Yes you can and again I see no reason why it's not a good idea. It'll do the job. BGP uses TCP sessions for routing data exchange so as long as IP is intact then BGP should peer (the rest of the BGP config not withstanding ;-))

Yes

Its been a while, but my recollection is that quagga has a main daemon and then the bgp, rip or ospf daemon, so you need both for the routing functionality to work.

Best thing to do is bench test it. slap linux on a spare laptop and set it up on the bench to peer to a router.

Cheers
