Hi all,

The subject is using link aggregation with RSVP. Or just generally the subject of how best to handle multiple parallel links between adjacent routers in a MPLS network. I'm hoping the list can provide guidance on the best practise for this, or point me to useful material.

The context is outside of a data centre, in the core of a national carrier network (P/P and P/PE links).

Link aggregation is the simplest option, but I am weary there may be problems with this approach. E.g. with the hashing algorithms and how this might impact on reported versus actual bandwidth for constrained LSP set up. Or with fast reroute, or failover from primary to secondary LSPs, when one of the links in the bundle fails.

Thoughts, insights, experiences, pointers, appreciated.

Cheers
Kris
