Subject: RE: OSPF-EIGRP Interesting Scenario
Ken,
You cannot change the distance of External EIGRP on a per prefix
basis. Instead, simply change the distance under OSPF for these routes.
First create an access-list that matches the prefixes:
Access-list 1 permit 1.0.0.0
Access-list 1 permit 2.0.0.0
Access-list 1 permit 3.0.0.0
Access-list 1 permit 4.0.0.0
Then change the distance. We'll use a neighbor address of any since it
doesn't matter in this case:
Router ospf 1
Distance 171 0.0.0.0 255.255.255.255 1
This says: change the distance of prefixes in access-list 1 learned from any
neighbor to 171.
P.S. I'll take you up on that offer of the English lager ;)
HTH,
