VRRP and VRRP-E parameters
VRRP and VRRP-E parameters
Table 276 lists the VRRP and VRRP-E parameters. Most of the parameters and default values are
the same for both protocols. The exceptions are noted in the table.
TABLE 276 VRRP and VRRP-E parameters
Parameter Description Default For more
information
Protocol The Virtual Router Redundancy Protocol (VRRP) based on
RFC 2338 or VRRP-Extended, the Brocade-enhanced
implementation of VRRP.
Disabled
NOTE: Only one of
the protocols
can be
enabled at a
time.

VRRP or
VRRP-E router
The Brocade Layer 3 switch active participation as a VRRP
or VRRP-E router. Enabling the protocol does not activate
the Layer 3 switch for VRRP or VRRP-E. You must activate
the switch as a VRRP or VRRP-E router after you configure
the VRRP or VRRP-E parameters.

Virtual Router
ID (VRID)
The ID of the virtual router you are creating by configuring
multiple routers to back up an IP interface. You must
configure the same VRID on each router that you want to
use to back up the address.

Virtual Router
IP address
This is the address you are backing up.
• VRRP – The virtual router IP address must be a real
IP address configured on the VRID interface on one
of the VRRP routers. This router is the IP address
Owner and is the default Master.
• VRRP-E – The virtual router IP address must be in
the same subnet as a real IP address configured on
the VRRP-E interface, but cannot be the same as a
real IP address configured on the interface.

VRID MAC
address
The source MAC address in VRRP or VRRP-E packets sent
from the VRID interface, and the destination for packets
sent to the VRID:
• VRRP – A virtual MAC address defined as
00-00-5E-00-01-<vrid> for IPv4 VRRP, and
00-00-5E-00-02-<vrid> for VRRP v3. The Master
owns the virtual MAC address.
• VRRP-E – A virtual MAC address defined as
02-E0-52-<hash-value>-<vrid> for IPv4 VRRP-E and
IPv6 VRRP-E, where <hash-value> is a two-octet
hashed value for the IP address and <vrid> is the ID
of the virtual router.
