• Question 60:

  An operations engineer from AS 2000 must deploy this inbound routing policy.

  1.

  Based on RFC1998, modify the local-preference value for prefixes containing BGP community values 2000.90 and 2000:110

  2.

  Strip any BGP community of the BGP prefixes received from customers that are in the range between 2000:1 and 2000:2000. Any other BGP community values must not be removed

  3.

  Apply 2000:1003 BGP community value, which indicates that the BGP prefix is learned from a customer Which configuration accomplishes this BGP routing policy?

  A. route-policy CUSTOMER-COMMUNITIES if community matches-any (2000:90) then set local-preference 90 elseif community matches-any (2000:110) then set local-preference 110 endif if community matches-any (2000:[1..89], 2000:[91..109], 2000:[111..2000]) then delete community all endif set community (2000:1003) end-policy
  B. route-policy CUSTOMER-COMMUNITIES if community matches-any (2000:90) then set local-preference 90 elseif community matches-any (2000:110) then set local-preference 110 endif delete community in (2000:[1…2000]) set community (2000:1003) end-policy
