Alcatel Unleashed

Hi,

I have activated ecmp in 2 routers with 2 equal cost paths. Then i created 2 epipes bind them to 2 different sdps and extended them to a vpls service. however load balancing between ports doesnt happen. All traffic go through one path. But LFIB also shows to ldp bindings.

ECMP is a routing feature, not a MPLS feature.

You can have multiple routes for OSPF or ISIS protection. But LDP won't ever use that. LDP is hop by hop MPLS, versus RSVP which uses an entire path from the beginning with protection features like secondary paths and/or FRR.

LDP only cares about getting to the next hop router.
