The Per-VRF Assignment of BGP Router ID feature introduces the ability to have VRF-to-VRF peering 
in Border Gateway Protocol (BGP) on the same router. BGP is designed to refuse a session with itself 
because of the router ID check. The per-VRF assignment feature allows a separate router ID per VRF 
using a new keyword in the existing bgp router-id command. The router ID can be manually configured 
for each VRF or can be assigned automatically either globally under address family configuration mode 
or for each VRF.
