HI,
about the question 2, you mean the route-map will use
destination address? I think it different. If you see
all the routing protocol format, the advertisint
router's update has a field that includes the
destination he can reach, in this case, does this mean
that when a router get a packet (suppose the router
enable a route map), the router then will check this
field ( the updated destination ip address field) for
the route-map to work?
regards
michael
