Licensing Requirements and Limitations for VRRP

Licensing Requirements and Limitations for VRRP

Involved Network Elements


Licensing Requirements

VRRP configuration is a basic feature of a router and is not under license control.

Feature Limitations

When configuring VRRP on the router, pay attention to the following points:
  • VRRP groups must use different virtual IP addresses. The virtual IP address of a VRRP group must be on the same network segment as the IP address of the interface where the VRRP group is configured.
  • The devices in a VRRP group must be configured with the same VRID.
  • Different interfaces can be bound to the same VRRP group.
  • If both VRRP and static ARP are configured on a Dot1q termination sub-interface, QinQ termination sub-interface, or VLANIF interface on a device, an IP address mapped to a static ARP entry cannot be used as a virtual IP address. If a VRRP virtual IP address is an IP address mapped to a static ARP entry on the device, the device generates incorrect host routes, affecting traffic forwarding.
  • If devices in a VRRP group use different VRRP versions, VRRP Advertisement packets may fail to be forwarded.
