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).
