Vishal,
You mentioned removing your distribution list and everything seems to be
normal, I interpret this to mean that you no longer see any instability in
your routing table. Does your debug ip routing output show stability across
your other routers when you have this problem occuring?
Have you considered looking at your debug ip routing output to see what the
reason for withdrawl is? You are our eyes on this, as we have no configs or
output to actually examine.
If you can get to a point of seeing why your routes are being withdrawn both
OSPF and BGP we can probably narrow this down to a resolution.

Subject: Routing issue
Hi all,
Iam facing a weird problem.
I have a router running ospf and ibgp.
And i have a distribute-list which allows only a default route from the
neigbour in ospf domain.
And Iam accepting all the internal routes via IBGP.
My routing table should show the internal routes via IBGP with the metric
of 200.
But the problem happening is the routing updates are continously changing
between ospf and bgp.
for a movement I get only default route via ospf and next movement I get all
the internal routes via IBGP.
As soon as remove distribute-list from ospf and accept the whole network via
ospf , the things are stable.
Well i also have more ospf neigbour , to a different router but it has
higher cost and it never appears in the routing table.
Any ideas ?
Cheers
Vishal
