Halabi, pg. 317:
Router bgp 1
neighbor INTERNALMAP peer-group
neighbor INTERNALMAP remote-as 1
neighbor INTERNALMAP route-map INTERNAL out
neighbor INTERNALMAP filter-list 1 out
neighbor INTERNALMAP filter-list 2 in
neighbor 172.16.11.1 peer-group INTERNALMAP
neighbor 172.16.13.1 peer-group INTERNALMAP
My question is this...I had always assumed that you couldn't use both an
outbound filter and an outbound route-map to the same neighbor...I based
that assumption on the fact that the route-map itself could act as a
filter...According to Halabi, however, this is an acceptable configuration,
so which logic is processed first? What if I incorporate an AS-path filter
in an outbound route-map that explicitly permits traffic that was explicitly
denied by the AS-path list referenced in the filter-list command?
Thanks in advance for any help,
Jack
