Hello guys,
Our network is currently running Quagga. We have 2 BGP peers - one main, which receives full route tables and one as backup, which receives default route only. The main one has a couple of sessions running - one for international traffic and one for local + backup sessions for both. Second one has main session and a backup session. Backup sessions go to different provider routers, of course.
Say, something like this:
Main Uplink
AS 1000
neighbor1: 10.10.0.1 - INT Router1
neighbor2: 10.10.0.2 - INT Router2
neighbor1: 10.10.0.3 - LOCAL Router1
neighbor2: 10.10.0.4 - Local Router2
Backup uplink
AS2000
neighbor1: 10.10.1.1 - INT/Local with default route only to Router1
neighbor2: 10.10.1.2 - INT/Local with default route only to Router2
My IP assignments:
Main uplink: 10.20.0.1
Backup uplink: 10.30.0.1
These both go through a switch, however we will ignore it at the moment. The preference is as follows: Local: 120, INT: 100, backup: 80
We also have some deny rules:
ip prefix-list INVALID_PREFIXES seq 10 permit 0.0.0.0/0 ge 25
ip prefix-list INVALID_PREFIXES seq 20 permit 10.0.0.0/8 le 32
ip prefix-list INVALID_PREFIXES seq 30 permit 127.0.0.0/8 le 32
ip prefix-list INVALID_PREFIXES seq 40 permit 172.16.0.0/12 le 32
ip prefix-list INVALID_PREFIXES seq 50 permit 192.168.0.0/16 le 32
So the actual question is how to configure a similar scenario as this on ER Pro.
Say we have:
Eth0 - Main uplink
Eth1 - Backup Uplink
Eth3 - going to switch
On top of the BGP (which I actually can configure, but prefer to see some expert advice), I want to announce a network, split it in half (say /25s), put them in tagged vlans and send it to my switch via Eth3 for 2 different devices to use.
