Version Description
7.5.1.0 Introduced on the C-Series.
pre-6.1.1.0 Introduced on the E-Series.
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).
