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
).
