Thanks Scott, that makes perfect sense and also justifies why distance
changed only some of the routes. These routes were advertised by the
directly connected neighbor which was mentioned along with the distance
command.
Thanks again
Ajay

Works fine. In OSPF though, the item you put in the "distance" command line
as route source is NOT your directly connected peer. It's the router-id of
the advertising router. In other words, that value needs to match the
information in "show ip ospf database" and it'll work great.

Ajay,
I think you are referring to a IE scenario. There was a discussion about
this about few weeks back. You would be able to dig that from the archives.
Changing of OSPF AD for selected prefixes doesn't, apparently, work for all
IOS versions.
Regards,
Shine

Subject: Problem with Distance in OSPF
Hello,
I have some problems with changing the AD in OSPF. I am trying to change the
distance or some routes learned by a neighbor to 109. However when I see the
routing table, it seems that the AD is changed only for one network (which
is directly connected to neighnor). Please help me understand this behavior.
