master of all the virtual routers, using the priority command if necessary.
For SLB, a modification to VRRP is necessary. In this case, you need to backup the
VIP (in addition to a routing interface of the router). An interface on the VIP’s
subnet still has to be configured. The VIP will be configured as the Associated IP of
the VRRP.
Note: When two P333R-LBs are connected in a VRRP pair with Full NAT configured
on both, you need to configure different PIP address ranges for each P333R-LB.
