Hi All
A quick question, If I redistribute from 2 different routers, 1 route as E2 with the default metric of 20, and then on the other router a E1 with a metric of 20, and the router that's connected to them both sees the preferred route as the E1 route with a metric of 21, is this normal behaviour? does OSPF always prefer E1 over E2 no matter even if its a higher metric ?
cheers
