Maybe I'm misunderstanding your question, but if you want to change the
distance of a route, use the 'distance' command. Under the EIGRP process,
you can change the distance for a specific route on a per neighbor basis.
Router EIGRP 1
distance 100 1.2.3.4 0.0.0.0 1
!
access-list 1 permit 10.0.0.0 0.255.255.255
This syntax sets the routes that match access-list 1 and are learned from
neighbor 1.2.3.4 to administrative distance 100. 1.2.3.4 is the neighbor
address, 0.0.0.0 is the wildcard your checking it against. All routes that
do not match ACL 1 are left at administrative distance 90.
I don't believe you can change the external distance on a per neighbor or
per route basis. *someone please correct me if I'm wrong. Use the 'distance
eigrp' command if you need to change the distance of an external route.
