Hi John,
Bgp MED attribute is an non-transitive option + bgp announce best
metric, so when you want to set this option in a redundant ebgp peering
sessions with different routers, you have to care both peers the same
options relatively. Probably you did step-1 and hadn't considered step-2, or
I understood the problem wrong :)
I mean (pseudo)
step-1)
R1
prefix-list choosen_path
route-map MED seq 10
match choosen_path
set med 100
route-map MED seq 20
set med 0
step-2)
R2
prefix-list choosen_path
route-map MED seq 10
match choosen_path
set med 0
route-map MED seq 20
set med 100
