I am using GNS3 For a topology as in attachment. I configure EIGRP on all routers. R! and R2 has 2 link with same bandwidth (1544). R1 routing table show both path due to same metric. But when i change bandwidth (3544) on s0/1 on R1, metric of that link does not change. R1 remain show two path.
But when i Configure same topology with all fast ethernet link, the metric changes on bandwidth change of F0/0 on R1 and it show only one path after bandwidth change.
