Hi,
I have the following routes need to be advertised through eBGP:
10.0.11.254/24
200.11.[1-15].254/24
I have the command:
network 10.0.11.0 mask 255.255.255.0
network 200.11.0.0 mask 255.255.0.0
but only network 10.0.11.0 is shown when "show ip bgp", can anyone help ?
Solved! Go to Solution.

Hello, BGP won't advertise any prefixes unless an exact match exists in its RIB. In your case you'll either need to receive a summary route for those networks and then advertise that or you'll have to add 15 network statements for all of these subnets. For instance,
network 200.11.1.0 mask 255.255.255.0
network 200.11.2.0 mask 255.255.255.0 and so on.
But the routes need to be present in you RIB first.
