I am trying out OSPF Virtual link configs. Here is the scenario:
R1 -------R2-------R4 -----R6
R1 is in area 0 (serial 1)
R2 left link (s1)is area 0, right link (token0)is area 1
R4 left (token 0)is area 1 and right (serial 1)is area 6.
R6 left (serial 0) is in area 6 and has loop back 0 in area 6.
I configured V-link between R2 and R4 to connect area 6 (on R6) to R2
(the ABR). V-link comes up good but I cannot see the routes between R2
and R4 (198.132.24.0 ) and the loopback of R2 (in area 1).
So all the transit networks routes did not make it the area 6 router
R6. What do I need to do to bring in those routes.
Below are the related configs.
****** BTW there are other networks on the left of R1 and I can see
all those routes on R6 ****** not included in the sh ip routes to keep
the output easier to read.
Any ideas ??
Thanks all for the help
