Example
Define a community-list numbered as 1, and allow the autonomous system
number to contain the routing information of 100 and 200. Then, the
route-policy named test is defined. The node No.10 of the route-policy defines a
if-match clause, which quotes the definition of the community-list.
[3Com] ip community-list 1 permit 100:200
[3Com] route-policy test permit node 10
