Does the iBGP peers need to be directly connected?

Hi
adding to the disscussions above
no IBGP peers don't have to be connected..but each router must know a route to the ID of the peer router via IGP running accross the network.
ussually IBGP peers run on the Loopback interfaces as an ID for the Router.
so each router must be able to reach the loopback of the other router( ID)
hope this helps

you do need a full mesh , you do not need to have direct connections they can be connected via tunnels .

Hi
There are two concepts to address this issue. Route Reflectors & Confedrations. This technique allows you to use partial mesh topology betweem iBGP peers.For more clarity make use of this URL

What everyone else seems to be responding with is referring to ibgp perring. I believe your question is whether ibgp peers can have non ibgp routers in between and yes they can. They do not need to be directly connected. There can be any number of interior routers running an igp connecting two ibgp peers. They do need to be able to reach each other so they have to be running the igp that will give them a route to the peer.
