R3102-R3103-HP 6600/HSR6600 Routers Layer 2 - LAN Switching Configuration Guide

136
• On a GARP-enabled network, each port maintains its own Hold, Join, and Leave timers, but only
one LeaveAll timer is maintained on each router. This LeaveAll timer applies to all ports on the
router.
• The value ranges for the Hold, Join, Leave, and LeaveAll timers are dependent on one another.
See Table 18
for their dependencies.
• Set the LeaveAll timer greater than any Leave timer and not smaller than its default value, 1000
centiseconds. Each time a LeaveAll timer expires, a network-wide re-join occurs.
• A router sends LeaveAll messages at the interval set by its LeaveAll timer or the LeaveAll timer on
another router on the network, whichever is smaller. This is because each time a router on the
network receives a LeaveAll message it resets its LeaveAll timer.
• To keep the dynamic VLANs learned through GVRP stable, do not set the LeaveAll timer smaller
than its default value, 1000 centiseconds.
