RP/0/RP0/CPU0:router(config-as)# end-set
RP/0/RP0/CPU0:router(config)# as-path-set AS_SET2
RP/0/RP0/CPU0:router(config-as)# ios-regex '_42$',
RP/0/RP0/CPU0:router(config-as)# ios-regex '_47$'
RP/0/RP0/CPU0:router(config-as)# end-set
2. Configure a route policy with wildcards to refer to the AS-path sets.

RP/0/RP0/CPU0:router(config-rpl)# if as-path in as-path-set* then pass else drop endif
RP/0/RP0/CPU0:router(config-rpl)# end-policy
