Re: Differene between E1 & E2 Routes in OSPF

E1 routes indicate cumulative cost to reach the destination i.e. int indicates cost to reach ASBR + cost to destination from ASBR.

E2 route reflects cost only from the ASBR to destination. This is the default used by ospf for redistribution.

And if I may add to above replies, E2 is the default for redistribured routes.
