Anycast IP setup

So, I’ve made some progress on this, but still trying to workout some stuff.

I have a server behind router1, which I’ve gone ahead and installed quagga on it. After that, I configured that server so that it uses ospf to advertise the anycast IP I configured on the loopback interface (192.168.51.20).

Progress:

router1 can now see 192.168.51.20 (anycast IP) being advertised:

---

@router1:~$ show ip route | grep 192.168.51.20
O>* 192.168.51.20/32 [110/30] via 192.168.2.29, eth1, 00:16:53

What I’m still trying to figure out, is how router2 (connected via GRE tunnel to router1), can see that 192.168.51.20/32 OSPF route shown on router1.

On router1, I’ve already added ‘192.168.51.20/32’ (also tried with .0/24) network to my OSPF area, but still no luck. If anyone had has ideas on how I can get the 192.168.51.20/32 OSPF route to be shown on router2, that would be very much appreciated.

I bet you don’t have your GRE Subnet in OSPF Network configuration…

Are both R1 and R2 in same ospf area? Can you possibly post ospf configuration on both R1 and R2?

By the way - If you have time to try something new - instead of Quagga on your server try - http://bird.network.cz it should have smaller HW requirements.
