Usage
Information
The community list used in the set comm-list delete command must be configured so that each
filter contains only one community. For example, the filter deny 100:12 is acceptable, but the filter
deny 120:13 140:33 results in an error.
If the set comm-list delete command and the set community command are configured in the
same route map sequence, the deletion command (set comm-list delete) is processed before the
insertion command (set community).
