I would use a filter list over a route map in this case.
You can only specify a single route-map and filter list per neighbor and the
filter list is designed for as_path filtering. So why waste a route-map to
do the same thing - you may need the route-map for other things - e.g.
communities, setting local pref etc.

Subject: Bgp filter-list or route-map?
Finishing up lab one from Cisco CCIE Lab Practice Kit, by Satterlee and
Hutnik.
Small Part of scenario is as follows:
As200---------------As300
- -
- -
- -
----As100----
"As100 should only accept local routes from As300. All other routes
should be accepted via As200."
Note: R2 is in As100 and neighbors with R6 which is in As300. As100
connects to both As200 and As300.
Recommended Answer.
R2(config)# ip as-path access-list 1 permit ^300$
R2(config)# route-map Accept_Local permit 10
R2(config-route-map)# match as-path 1
R2(config-router)# neighbor 152.1.11.2 route-map Accept_Local in
Would this not work just as well?
R2(config)# ip as-path access-list 1 permit ^300$
R2(config-router)# neighbor 152.1.11.2 filter-list 1 in
Is there a reason to use route-map over a filter-list?
Thanks
Dan
