Hi groups
I have three 2501s connect over FR. Router A is hub, and B,C are spoke. The
subnet is 172.30.100.0/28. On router A, I use a subinterface
point-to-multipoint. On B and C, I don't use subinterface. I install OSPF on 3
routers. Router A established adjacent with B and C. The configurations on B
and C are the same. But only router B receive show the update from router A in
its routing table. Router C doesn't have any OSPF routes in its routing table.
I check in Router C 's OSPF topology database and see all the routes that
router C received from Router A but they aren't shown up in routing table.
There is no connection between B and C.
I don't understand why ? Does anyone catch this problem ? Can you give me some
advices ?
Thanks
