Answer: A
Explanation:
http://www.cisco.com/en/US/docs/ios_xr_sw/iosxr_r3.7/routing/command/reference/rr37plc y.html
Examples In the following example, the policy CustomerIn applies the route-policy SetLocalPref to conditionally set the local preference on a route. The parameters 20, 30, 40, and 50 are passed to the parameterized policy SetLocalPref, where the local preference is set to:
.20, if the community 217:20 is present in the route
.30, if the community 217:30 is present in the route
.40, if the community 217:40 is present in the route
.50, if the community 217:50 is present in the route
RP/0/RP0/CPU0:router(config)# route-policy SetLocalPref ($lp0, $lp1, $lp2, $lp3, $lp4) RP/0/RP0/CPU0:router(config-rpl)# if community matches-any ($lp0:$lp1)then RP/0/RP0/CPU0:router(config-rpl-elseif)# set local-preference $lp1 RP/0/RP0/CPU0:router(config-rpl-elseif)# elseif community matches-any ($lp0:$lp2) then RP/0/RP0/CPU0:router(config-rpl-elseif)# set local-preference $lp2 RP/0/RP0/CPU0:router(config-rpl-elseif)# elseif community matches-any ($lp0:$lp3) then RP/0/RP0/CPU0:router(config-rpl-elseif)# set local-preference $lp3 RP/0/RP0/CPU0:router(config-rpl-elseif)# elseif community matches-any ($lp0:$lp4) then RP/0/RP0/CPU0:router(config-rpl-elseif)# set local-preference $lp4 RP/0/RP0/CPU0:router(config-rpl-elseif)# endif RP/0/RP0/CPU0:router(config-rpl)# end-policy RP/0/RP0/CPU0:router(config)# route-policy CustomerIn($cust) RP/0/RP0/CPU0:router(config-rpl)# apply SetLocalPref ($cust, 20, 30, 40, 50) RP/0/RP0/CPU0:router(config-rpl)# end-policy RP/0/RP0/CPU0:router(config)# route-policy Cust_217 RP/0/RP0/CPU0:router(config-rpl)# apply CustomerIn(217) RP/0/RP0/CPU0:router(config-rpl)# end-policy
