Layer 3 Routing Commands 1272
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

Successive invocations of the command are additive in that they add to the
configured communities up to the maximum.
If more than the maximum allowed communities are configured, the excess
entries are ignored.
