Internal cost to the advertising router is used as a tie break here. Hence, the internal cost to the ASBR's would need to be the same for ECMP to take place. >ROUTER#sh ip route x.y.z.w/24 >Routing entry for x.y.z.w/24 > Known via "ospf 500", distance 110, metric 20, type >extern 2, forward metric 8 > Last update from a.b.c.d on ATM1/0.109, 00:07:02 ago > Routing Descriptor Blocks: > * X.Y.Z.W, from A.B.C.D, 00:07:02 ago, via >ATM1/0.109 > Route metric is 20, traffic share count is 1 > >What's the meaning of "forward metric" value?

Just look in the routing table for your cost to each router and see if they are the same. >Why? >Thanks!!! > > > >_______________________________________________________________ >Yahoo!
