Hi Everyone, Have a PE that has 2 "interpop" connections back to 2 other PE's...both links running ospf+mpls. Link 1 (primary) has ip ospf cost 201 Link 2 (secondary has ip ospf cost 202 But traffic egressing from this PE is load balancing(per session) across the 2 links? If I do a sh ip route foo, it displays both paths, known via OSPF and route metric of 205? Hoping someone can explain why? (Are the ospf costs too close, and "other" attributes/metrics come into play, and the links are seen as equal?) Cheers. ---------------------------------------------------------------------------- ---------------------------------------------------------------------------- ------------------------------ Please give us a show ip route x.x.x.x and show ip ospf data x.x.x.x so that we can analyse the routing. How is your OSPF setup? Is each POP in its own area or are you running everything in area 0?
