[Xorp-users] Missing OSPF neighbours

Hi,

Your config files worked fine for me (I changed the interface addresses
for my setup and didn't include the static route). By the way I wouldn't
expect to see any ospf routes, the two routers can already reach each
other.

    Dinesh> I am really not sure why there is no adjacency between these two PCs. I have checked the reachability between them also.
