EPSR TOPOLOGY CHANGE

epsr topology-change

Overview Use this command to allow the given EPSR instance to accept notifications from
other topology protocols, namely G.8032, for Topology Change Notifications
(TCN).
Use the no variant of this command to return the EPSR instance to where it does
not accept TCNs from the other specified protocol, and as a result does not send
out a "flush FDB" message.
epsr <epsr-name> topology-change g8032
Syntax
no epsr <epsr-name> topology-change g8032
Default The default value is no notifications are accepted and in turn no "flush FDB"
messages are sent.
Mode EPSR Configuration
Usage The purpose of this command is to allow EPSR to accept notifications from other
topology protocols, namely G.8032, about Topology Change Notifications (TCN).
Once EPSR accepts the TCN, it will in turn notify the other nodes on the EPSR ring
to perform an FDB flush.
Example To configure an EPSR instance named "red" to accept G.8032 TCNs, use the
following command:
awplus(config-epsr)#
To configure an EPSR instance named "red" to no longer accept G.8032 TCNs, use
the following command:
awplus(config-epsr)#
