Syntax

Description

The Routing Engine performs one-by-one state change for subsequent VRRP groups. Every time there is a state change, and the new state for a particular VRRP group is primary, the Routing Engine generates appropriate VRRP announcement messages. When the first VRRP group detected by the Routing Engine changes state, and the new state is primary, the Routing Engine generates appropriate VRRP announcement messages. The Packet Forwarding Engine is informed about the state change, so that hardware filters for that group are reprogrammed without delay. The new primary then sends gratuitous ARP message to the VRRP groups.

Options

group-id

VRRP group identifier. If you enable MAC source address filtering on the interface, you must include the virtual MAC address in the list of source MAC addresses that you specify in the source-address-filter statement. MAC addresses ranging from 00:00:5e:00:53:00 through 00:00:5e:00:53:ff are reserved for VRRP, as defined in RFC 2338. The VRRP group number must be the decimal equivalent of the last hexadecimal byte of the virtual MAC address.

Note:

Under certain circumstances, the group identifier that you enter must be different from any other group identifiers that you configured for logical units of this same physical interface. See Configuring Basic VRRP Support for more information.
