This was a thread about a month ago. The following works as an OR
ip as-path access-list 1 permit _3500_
ip as-path access-list 2 permit _2400_
route-map AND permit 10
match as-path 1 ---- > this shows up as match as-path 1 2
match as-path 2 in the config file!!! I tried this.
set metric 5000
As I recall, if the original solution follows the format suggested at the
end of a long discussion. The original solution is shown below and further
on in this e-mail thread.
ip as-path access-list 1 permit _3550_(.*)2400_|_2400_(.*)3500_

I believe that the as-path list will also match paths containing:
"3500" and "12400"
"2400" and "43500"
ie the (.*) also allows other characters to appear before the 2400 or
3500...
Anyone agree?
Why not use something simple like:
ip as-path access-list 1 permit _3500_
ip as-path access-list 2 permit _2400_
route-map AND permit 10
match as-path 1
match as-path 2
set metric 5000
Anything wrong with this logic?
