Defining apply Clauses
for the Routing Policy

OLICY ONFIGURATION
To do...
Match routes having the specified route type
Match RIP, OSPF, or IS-IS routes having the
specified tag value
The if-match clauses of a route-policy are in logic AND relationship, namely,
■
routing information has to satisfy all if-match clauses before being executed
with apply clauses.
You can specify no or multiple if-match clauses for a routing policy. If no
■
if-match clause is specified, and the routing policy is in permit mode, all
routing information can pass the node; if in deny mode, no routing
information can pass.
A routing policy should use a non VPN ACL for filtering.
■
The differences between defining if-match clauses for IPv4 and IPv6 routing
■
policies are commands for matching the destination, next hop and source
address.
To define apply clauses for a route-policy, use the following command:
