Question of path attributes for MP-REACH-NLRIs

  • From: Janardan Ramesh <JRamesh@shastanets.com>

When an MPLS BGP speaker receives an update from
a peer, what are the path attributes relevant to the MP-REACH-NLRIs.

Am I right in assuming that AS-Path, MEDISC, NEXTHOP (since it
is contained within MP-REACH-NLRI), ATOMIC, AGGREGATOR
are not relevant.

Local preference might not be relevant since a prefix from two peers
come in with different RDs anyway.

That leaves ORIGIN, Community, Route-Relector-Originator-ID and
RR-Cluster-ID. 

Is it OK just to store the relevant attributes?

Thanks in advance

Ramesh
