I have three routers:
R1- area 0 -R2- area 1 -R3- area2
There is a virtual link configured over area 1 on R2 and R3.
R1 has 8 ospf interfaces with contiguous IPs 60.60.X.3 X=0..7
R2 has a range configured to condense them from area 0 into area 1:
router ospf 1
area 0.0.0.0 range 184.108.40.206 255.255.248.0
When the virtual link is up, R2 redistributes ALL 8 routes as LSAs into area 1! (seen with show ip ospf database)
When I disable the virtual link on R3, R2 does the condensation and only 1 LSA is advertised into area 1.
Do you know what document states that if on an ABR like R2, if the destination area like area 1 has a virtual link up in it, the routes are NOT condensed INTO it? (this seems to be the exact cisco behaviour)
There might be some common sense logic that when the virtual link is up, all routers are in area 0 and no condensation is needed, but I would like to understand the theory also.
