To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

The leave-all timer parameter controls how often the leave-all messages are sent. This forces all the peers to re-declare all the attributes, thereby replaying any registrations or deregistrations that may be lost.

Command Default

30 seconds

Command Modes

Flood optimization for PBB over VPLS global configuration submode.

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

The leave-time command controls how long registrations stay in the leaving state before being removed; that is, it controls when the garbage collection of stale registrations is performed after unregistration.

The leaveall-time and the leave-time commands together control the garbage collection.

The IEEE specification states that the value of the leave-time command must be less than the value of the leaveall-time command.

However, in Cisco IOS-XR, processing outages of several seconds can occur during a process restart or Router Processor Fail-Over (RPFO) leading to a loss of messages.

Therefore, a greater default leave-time value (thrice that of the leaveall-time value command) increases the robustness of the Multiple MAC Registration Protocol (MMRP) during packet loss or system outage.
