VRRP parameters for
Router 2
Enable VRRP You must explicitly turn virtual routing on for each virtual router in order
to enable your virtual router to become an active component of VRRP on
your network. Use
ip vrrp mode
in the Administration console or use
the IP VRRP Mode form in the Web Management console to enable VRRP.
If you want to redefine a VLAN that is being used for a virtual router, you
must remove the virtual router, then remove the IP interface used by the
virtual router, then finally remove the VLAN.
