Zhang UCLA - March 8, 2010 + August 31, 2010 Auto-Configuration in Virtual Aggregation - draft-ietf-grow-va-auto-01.txt + draft-ietf-grow-va-auto-02.txt Abstract Virtual Aggregation as specified in [I-D.ietf-grow-va] requires configuration of a static "VP-List" on all routers. The VP-List allows routers to know which prefixes may or may not be FIB- installed. This draft specified an optional method of determining this that requires far less configuration. Specifically, it requires the configuration of a "VP-Range" in ASBRs connected to transit and peer ISPs. An Extended Communities Attribute is used to convey to other routers that a given route can be FIB-suppressed.
