Abstract:
BGPLS provides a mechanism by which Link state and traffic
engineering information can be collected from internal networks and
shared with external network routers using BGP. BGPLS defines a new
Address Family to exchange this information using BGP.
BGP Optimal Route Reflection (ORR) provides a mechanism for a
centralized BGP Route Reflector to acheive requirements of a Hot
Potato Routing as described in Section 11 of [RFC4456]. Optimal
Route Reflection requires BGP ORR to overwrite the default IGP
location placement of the route reflector; which is used for
determining cost to the nexthop contained in the path.
This draft augments BGPLS and defines a new extensions to exchange
cost information to next-hops for the purpose of calculating best
path from a peer perspective rather than local BGP speaker own
perspective.
