Question

ASN 65001 is peering with ASN 65002 to exchange IPv6 BGP routes.

All routes that originate in ASN 65001 have a standard community value of 65001:100, and ASN 65002 is allowed to advertise only 2001:db8:aaaa::/48

An engineer needs to update the ASN 65001 route-filtering configuration to meet these conditions: -> Looped routes into ASN 65001 and routes that have traversed 10 or more ASNs must be denied.

-> Routes accepted into ASN 65001 must be assigned a community value of 65001:200

Which configuration must be engineer apply to the ASN 65001 border router? A.

route-policy PEER-AS65002-IN if as-path length ge 10 then drop endif if as-path passes-through °65001" or community matches-any (65001:100) then drop endif if destination in (2001:db8:aaa pass endif set community (65001:200) end-policy /48) then

B.

route-policy PEER-AS65002-IN if as-path length ge 10 then drop endif if as-path passes-through °65001" or community matches-any (65001:100) then drop endif if destination in (2001:db8:aaai set community (65001200) else drop endif end-policy /48) then

C.

D.

route-policy PEER-AS65002-IN > if as-path length ge 10 or as-path passes-through '65001' or community matches-any (65001:100) then if destination in (2001:db8:aaa: done else drop endif ‘set community (65001:200) end-policy
