[quagga-users 14170] Fwd: Route Server Advertised Routes

[Eric Dean]

I am running a route server on a public exchange. I have to setup per the
tutorial. I don't have a way to verify what routes I am sending each
member. When I do 'show ip bgp neigh w.x.y.z advertised-routes' nothing
shows. My peers confirm they are receive routes and debug bgp updates show
them being sent. My 'show ip bgp x.y.z.0' also doesn't show my community
tags.

Does the route-server-client and/or import/export function change something
with those commands?

you probably want to use the "show ip bgp rsclient" command here.

Yes.

All routes received from all neighbors are added to the "Main" RIB.

All routes received from an rs-client are *also* added to every other rs-client's own RIB.

An rs-client will receive routes only from its own RIB -- it receives no routes from the "Main" RIB. (Only not-rs-clients receive routes from the "Main" RIB.)

'show ip bgp neigh w.x.y.z advertised-routes' shows what has been advertise from the "Main" RIB... ie, for an rs-client, bupkis. You could argue that this is a bug, and I might well not disagree with you.

'show ip bgp rsclient w.x.y.z' will show the state of the rs-client RIB.
