■
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.
