Title: RE: OSPF - Is the Virtual Link the Problem?
it seems u r doing authentication in area 0. so you need to configure
authentication for the virtual link as well.
example, you may configure following for r1:
area 0 authentication message-digest
area 11 virtual-link 193.255.255.17 message-digest-key 1 md5 cisco
for r2:
area 11 virtual-link 55.255.255.17 message-digest-key 1 md5 cisco

Subject: OSPF - Is the Virtual Link the Problem?
I have the following topology:
area 1 area 2 area 3
ROUTER 1
area 11
ROUTER 2 - - - - area 0- - - - ROUTER 3
area 8 area 9
Routes to area 1,2,&3 are not showing up in my route table? I have
spent
entirely too much time trying to figure this one out - Please Help!
- The virtual link is up going both ways
- The area 1,2,3,8,&9 are loopback interfaces
- There is a neighbor adjacency between R1 and R2
- The network type on R1 and R2 is PtoP and I changed it to broadcast
w/
R2
DR, still no luck.
Here's the relevant config from R1:
router ospf 18
area 11 virtual-link 193.255.255.17
network 11.255.255.16 0.0.0.15 area 11
network 55.255.255.4 0.0.0.3 area 1
network 55.255.255.8 0.0.0.7 area 2
network 55.255.255.16 0.0.0.15 area 3
Here's R2:
router ospf 17
redistribute eigrp 1 metric 100 subnets
network 10.255.255.16 0.0.0.15 area 0
network 11.255.255.16 0.0.0.15 area 11
network 193.255.255.16 0.0.0.15 area 8
network 193.255.255.8 0.0.0.7 area 9
area 0 authentication message-digest
area 11 virtual-link 55.255.255.17
