Use Wildcards For Routing Policy Sets
This section describes examples of configuring routing policy sets with wildcards.
Use Wildcards for Prefix Sets
Use the following example to configure a routing policy with wildcards for prefix sets.
1
Configure the required prefix sets in the global configuration mode.
RP/0/RSP0/CPU0:router(config)# prefix-set pfx_set1
RP/0/RSP0/CPU0:router(config-pfx)# 1.2.3.4/32
RP/0/RSP0/CPU0:router(config-pfx)# end-set
RP/0/RSP0/CPU0:router(config)# prefix-set pfx_set2
RP/0/RSP0/CPU0:router(config-pfx)# 2.2.2.2/32
RP/0/RSP0/CPU0:router(config-pfx)# end-set
2
Configure a route policy with wildcards to refer to the prefix sets.
RP/0/RSP0/CPU0:router(config)# route-policy WILDCARD_PREFIX_SET
RP/0/RSP0/CPU0:router(config-rpl)# if destination in prefix-set* then pass else drop
endif
RP/0/RSP0/CPU0:router(config-rpl)# end-policy
This route policy configuration accepts routes with the prefixes mentioned in the two prefix sets, and drops
all other non-matching routes.
3
Commit your configuration.
RP/0/RSP0/CPU0:router(config)# commit
This completes the configuration of routing policy with wildcards for prefix sets. For detailed information on
prefix sets, see prefix-set, on page 474.
Use Wildcards for AS-Path Sets
Use the following example to configure a routing policy with wildcards for AS-path sets.
