Removing RADIUS Discovery
The VPLS service must be shut down in order to disable or remove RADIUS discovery from a
VPLS service.
When RADIUS discovery is disabled for a VPLS service, auto SDPs and auto SDP-bindings for
that VPLS are removed.
Remove a PE from VPLS
When a PE is removed from a VPLS service, the RADIUS server must be updated manually to
remove the PE from the membership database.
