In the Serial?
Remember that now you are running IP over PPP over Frame-relay, also If my
memory does not fails those kind of interfaces are by default are
point-to-point ospf network type so doing that would not help you much
Please I would like to see the following outputs
Show ip ospf interface brief
Show ip ospf interface
Show ip ospf neigh
Show ip ospf
Show ip ospf database
In both routers
Thanks!
Victor.-

Hi Victor,
After i input the command below, virtual link still down.
I dont kown why, because i think my configuration is already true.. may be
something about ospf type or election DR or BDR?? but i try make R6 serial
is ip ospf priority 0 and R5 still prioirty 1 but still virtual link not
making up..
