Use Wildcards For Routing Policy Sets
1 Configure the required AS-path sets in the global configuration mode.
RP/0/RSP0/CPU0:router(config)# as-path-set AS_SET1
RP/0/RSP0/CPU0:router(config-as)# ios-regex '_22$',
RP/0/RSP0/CPU0:router(config-as)# ios-regex '_25$'
RP/0/RSP0/CPU0:router(config-as)# end-set
RP/0/RSP0/CPU0:router(config)# as-path-set AS_SET2
RP/0/RSP0/CPU0:router(config-as)# ios-regex '_42$',
RP/0/RSP0/CPU0:router(config-as)# ios-regex '_47$'
RP/0/RSP0/CPU0:router(config-as)# end-set
2 Configure a route policy with wildcards to refer to the AS-path sets.
RP/0/RSP0/CPU0:router(config)# route-policy WILDCARD_AS_SET
RP/0/RSP0/CPU0:router(config-rpl)# if as-path in as-path-set* then pass else drop endif
RP/0/RSP0/CPU0:router(config-rpl)# end-policy
This route policy configuration accepts routes with AS-path attributes as mentioned in the two AS-path
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 AS-path sets. For detailed information
on AS-path sets, see
Use Wildcards for Community Sets
Use the following example to configure a routing policy with wildcards for community sets.
1 Configure the required community sets in the global configuration mode.
RP/0/RSP0/CPU0:router(config)# community-set CSET1
RP/0/RSP0/CPU0:router(config-comm)# 12:24,
RP/0/RSP0/CPU0:router(config-comm)# 12:36,
RP/0/RSP0/CPU0:router(config-comm)# 12:72
RP/0/RSP0/CPU0:router(config-comm)# end-set
RP/0/RSP0/CPU0:router(config)# community-set CSET2
RP/0/RSP0/CPU0:router(config-comm)# 24:12,
RP/0/RSP0/CPU0:router(config-comm)# 24:42,
RP/0/RSP0/CPU0:router(config-comm)# 24:64
RP/0/RSP0/CPU0:router(config-comm)# end-set
2 Configure a route policy with wildcards to refer to the community sets.
RP/0/RSP0/CPU0:router(config)# route-policy WILDCARD_COMMUNITY_SET
RP/0/RSP0/CPU0:router(config-rpl)# if community matches-any community-set* then pass else
drop endif
RP/0/RSP0/CPU0:router(config-rpl)# end-policy
This route policy configuration accepts routes with community set values as mentioned in the two
community 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 community sets. For detailed information
on community path sets, see
