Try removing the network statement, removing the route to null 0, putting
the network statement back in, and doing a hard reset on the bgp.

Hi,
I have tried using -network 172.16.1.0 mask 255.255.255.128
network 172.16.1.0 mask 255.255.255.0
Heres the output.

Keep trying.. You have to use given subnet on loopbacks :)
Send your last sh ru, sh ip rou, sh ip bgp su, sh ip bgp

So guys I am back with the same problem.
I have tried quite a number of combinations of network statements, but it
either does not advertise anything or just advertises the whole 172.16.0.0
subnet.
I guess it is then not such a good idea to use a bigger subnet for loopback
interfaces, so I will use 255.255.255.255 subnet for my loopbacks.
Smiles,
Mohit.

You may not use any static routes unless specifically said.

I suspect that it because the network you try to advertise is not in your
routing table. Try use show ip route on the local router. If you can not
see the network, then add a static route: ip route 172.16.1.7
255.255.255.128 null0 use show ip route to verify it appeares on the routing
table, then you would see it from the remote.
Hope this will solve your problem.
