Hey team,
Just playing around with OSPF and GRE tunnels and having no luck. Can
anyone help?
Router1's s1 interface is in area 12 as is router2's s0. Between R2
and R5 is area 51
(network 151.1.222.0/24). As you can see in order for area 12 to
communicate with the rest
of the ospf network it needs a virtual link beween r2 and r5. I did
that and it worked.
What i'm trying to do now is a GRE tunnel between r2 and r5. The tunnel
is up but r1 never
sees the routers that it did when the virtual-link was up. The tunnel
interfaces show up
can I ping the loopback on r5 from r2 and vice verase but r1 sees no
ospf routes.
R1--area12------R2--------area51------R5----------area0
(150.1.2.2) (151.1.5.5)
Below are the configs. Feel free to email me directly with my blunder
if you so desire.
