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