Nice point brought in picture..
I didnt knew this abt leak-map .. may be i was lucky that last time i
tried leak map i tried using a standard ACL ..
[1] My observation .. in case of BGP supress-map and unsupress-map ..
always we are supposed to use prefix-list in that route-map ..
extended ACL *might* not work ..
[2] Similarly .. when we use bgp inject-map command for conditional
route injection .. we are supposed to use prefix-list in both the
route-maps that we are defining ..
This 2nd point is documented as well
The exist-map argument specifies a route map that defines the prefix
that the BGP speaker will track. This route map must contain a match
ip address prefix-list command statement to specify the aggregate
prefix and a match ip route-source prefix-list command statement to
specify the route source.
Others .. please add your observations in this context so that we have
a handy list with us .
Thnx
Gaurav Madan.
