Me again with more CCNP studying. So in gns 3 I have the following topology:
R1 is running a multi vrf/multi ospf process. I'm trying to simulate something like what an ISP would potentially do. So the ospf adjacency between R1 and R3 comes up fine...and the other 2 do not. I have no clue what I'm doing wrong. Probably being stupid and missing something simple but I can't figure it out. Here's the configs:
R1:
R1#sh run int g1/0 Building configuration... Current configuration : 183 bytes ! interface GigabitEthernet1/0 description TO-R2 ip vrf forwarding R2 ip address 10.255.5.1 255.255.255.0 ip ospf dead-interval 3 ip ospf hello-interval 1 negotiation auto end R1#sh run int g2/0 Building configuration...

So again, the R3 stuff works fine. If I go on R1 and do
sh ip ro vrf R3
I get
R1#sh ip ro vrf R3
Routing Table: R3

and that just repeats.
I've already removed all the ospf instances on R1 and remade them, and I took all the cables out of GNS3 and re-did those as well. Not sure what I'm doing wrong.
