Connected ipv6 network not showing in routing tabe
I'm having connectivity problems on an ipv6 p2p frame relay network. In the foundation learning network, p800 or 801, there is a network diagram of four routers that I am trying to set up. However when setting up a router I am creating mulitple p2p interfaces
the dlci's are ok. but the 224 (originally 24 in the book but I thought there might be a bug with two digit Ipv6 addresses so I tried 3 digit inital prefixes). The 123 networks work fine but the other network doesn't work. The ip routing table doesn't show the 224 network
just for reference here is the other router that is connected to this one.
I am doing something wrong but I cannot see what. Anyone see? Let me know if more info is needed

Are you actually getting DLCI 302 from the FRSW?Currently reading:

Not to worry...I rebuilt each router including the frame relay switch and have it working now. Silly problems but you do learn from them. I had ipv6 unicast-routing enabled on the routers and the dlci's should have been correct but the dlci's on the frame relay switch were ambiguous, I had never changed them from when I got it just worked with what was on it. Turned out that some of the interfaces on the frame relay switch were shutdown. I did notice that if the link isn't up, the route doesn't get put in the routing table. Thanks for the assistance guys!! -

In the future, use show frame-relay pvc | i STATUS on the router.
This is a great shortcut to debug FR config issues. If you see "DELETED" that's bad. 95% of the time, it's because you configured the wrong DLCI on the router side. 5% of the time it's because the main interface is shutdown.Currently reading:
