Router Redundancy Using XRRP
Configuring XRRP
Configuration Rules
■ XRRP can be configured only on statically configured IP VLANs. VLANs
automatically created by GVRP cannot be used.
■ XRRP cannot be configured on the management VLAN or on any VLAN
that gets its IP address through DHCP or Bootp.
■ XRRP must be disabled before the Protection Domain number or the
router number configuration can be changed. Use the no xrrp command
to disable XRRP.
■ Dynamic reconfiguration – You should be aware that although XRRP can
be reconfigured while it is running, dynamic configurations can lead to
inconsistency between the two routers while the configuration changes
are in progress. This will potentially result in error log messages until the
configurations are consistent (for example, matched IP addresses for
primary on one side and secondary on the other). To avoid these logs,
disable XRRP while changing its configuration.
Use the no xrrp command to disable XRRP.
