I am testing VRRP and it seems to work very well. Below is my config
R1-3640 Primary Router
R2-3640 Secondary Router
S1-2960 Internal Switch
S2-29?? External Switch
I have a single ethernet drop from our colo provider, I will have it go into a switch then to each of my routers on FA0/0. The internal switch uses Gi0/1 for a link to R1 and Gi0/2 to R2 on the router port Fa1/0. VLANs are used from the router to hosted machines on S1. I have a public /24 for each VLAN grouping Windows and Linux servers on their own respective VLAN.
Currently there are no defined routes between the routers. Our upstream only points to R1 for our IP space which they are announcing for us.
Should I lose any of my links VRRP will take over for that link. What is the best way to make sure that traffic doesn't go to a router that has a dead link on another port? I thought about OSPF, but it might cause a route flap should VRRP drop and recover quickly.
I think it would be nice to have some type of routing between the 2 routers to allow traffic to flow during a link failure on another interface. We have a /22 on our network and I could setup something similar to this..
ip route 188.8.131.52 255.255.252.0 R2-Fa0/0 10
ip route 184.108.40.206 255.255.252.0 R2-Fa1/0 10
ip route 0.0.0.0 0.0.0.0 R2-Fa0/0 20
ip route 0.0.0.0 0.0.0.0 R2-Fa1/0 20
ip route 220.127.116.11 255.255.252.0 R1-Fa0/0 10
ip route 18.104.22.168 255.255.252.0 R1-Fa1/0 10
ip route 0.0.0.0 0.0.0.0 R1-Fa0/0 20
ip route 0.0.0.0 0.0.0.0 R1-Fa1/0 20
Should I look at doing route maps possibly?
