User Guidelines
A community list statement with no community values is considered a match
for all routes, regardless of their community membership. So the statement
ip community-list bullseye permit
is a “permit all” statement.
A community number may be entered in either format, as a 32-bit integer or a
pair of 16-bit integers separated by a colon, regardless of whether the ip bgp-
community new-format command is active. Up to 16 communities, including
the well-known communities, can be listed in a single command. Up to 32
statements may be configured with a given community list name. Up to 128
unique community list names may be configured.
Successive invocations of the command are additive in that they add to the
configured communities up to the maximum.
