Hi group,
I have 4 routers, A, B, C and D on an ethernet segment with each router's
ethernet interface configured to be in OSPF area 1. Routers A and B are ABRs
between area 0 and area 1. Router C is also an ABR between area 1 and area
2.
When I configured a virtual link between rtr C and B it doesn't work - the
output of show ip ospf virtual-link shows the v-link down. However, when I
configure the v-link between rtr C and A, it does work. I'm trying to figure
out why this is.
On rtr C, I did a show ip ospf nei and saw the following:
nei A Full/BDR
nei B 2way/DRother
nei D Full/DR
Also, when I ping trace between rtr C and B, it takes 2 hops, not 1 even
though both rtr C and B are on the same ethernet segment.
Given the above info, is it possible that a virtual link across an ethernet
segment has to be between a router and the DR or BDR on the segment?
Thanks in advanced. Jim
