Question #1

Refer to the Cisco IOS-XR route policy exhibit.

Which statement correctly describes this route policy?

A. The pass action is required after each of the set community statements to make this route policy functional.

B. If a route contains the 11:11 or 44:44 community, the router adds the 55:55 community and continues. Additionally, if the same route also contains the 22:22 community, the router also adds another 77:77 community to the same route.

C. If a route only has the 22:22 community, then no community will be added by the router.

D. If a route has both the 11:11 and 22:22 communities (or 44:44 and 22:22), the router adds the 55:55 community only.

E. If a route only has the 11:11 or 44:44 community, then no community will be added by the router.
