The BGP protocol is totally stateful. It does not use periodic refreshes
of state to synchronise BGP processes. A BGP speaker is therefore
required to send all its winning routes when a new session is
established.
The XORP BGP will send all the winning routes when a new session is
established.
Take a look in bgp/harness/test_peering2.sh, it contains tests to verify
that we handle sessions being brought up and taken down, it
also demonstrates how to add peerings using XRLs.
