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

B.
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.

C.
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.

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