the route.
community [no-advertise | no-export | no-export-
subconfed | <community_num>
{<community_num1> <community_num2> ….

the communities specified by the action statement.
Communities must be enclosed in double quotes ("").
community [add | delete] [no-advertise | no-export |
no-export-subconfed | <community_num>
{<community_num1> <community_num2> ….
