I bet this question has been posted many times.
assuming multicast is not blocked and the interface can do mulitcast, ospf
relationship between opsf network p2m and p2m-nb works, i got it labbed up and
I can’t see a problem with it. Is this right? Apart from show run is there
anyway to see that an interface is in p2m-nb; show ip ospf inter tells me that
the interface is Network Type POINT_TO_MULTIPOINT.
Many thanks
Fulvio
