Being a little new to 'production' BGP i have a scenario at my company that confuses me. We have 5 ibgp peers and 2 ebgp peers at two different NAPs.
The ibgp peers advertise routes to either other using a mix of network statements, null0 routes and redistribution.
Our ebgp speakers get their routes form the ibgp peers. Now, the ebgp speakers have a number of peering relationships each. However, they do not appear to advertise any routes. They do not have network statments, null0 routes or otherwise. All the have is a few peer groups and distribute lists/prefix lists.
My question is, how do the external peers get updates from our ebgp speakers if the network statement is not present under the BGP config on each ebgp speaker?
