Parameter Description
Virtual Router IP This is the address you are backing up.
address
No default.
•
•
VRID MAC The source MAC address in VRRP or VRRPE
address packets sent from the VRID interface, and the
destination for packets sent to the VRID.
•
•
Authentication The type of authentication the VRRP or VRRPE
type routers use to validate VRRP or VRRPE packets.
The authentication type must match the
authentication type the VRID's port uses with other
routing protocols such as OSPF.
•
•
Note: MD5 is not supported by VRRP or VRRPE.
Router type Whether the router is an Owner or a Backup.

Table 21.1: VRRP and VRRPE Parameters (Continued)
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.
VRRPE – The virtual router IP address must be
in the same sub-net as a real IP address
configured on the VRRPE interface, but cannot
be the same as a real IP address configured on
the interface.
VRRP – A virtual MAC address defined as
00-00-5e-00-01-<vrid>. The Master owns the
Virtual MAC address.
VRRPE – A virtual MAC address defined as
02-E0-52-<hash-value>-<vrid>, where <hash-
value> is a two-octet hashed value for the IP
address and <vrid> is the VRID.
No authentication – The interfaces do not use
authentication. This is the VRRP default.
Simple – The interface uses a simple text-string
as a password in packets sent on the interface. If
the interface uses simple password
authentication, the VRID configured on the
interface must use the same authentication type
and the same password.
Owner (VRRP only) – The router on which the
real IP address used by the VRID is configured.
Backup – Routers that can provide routing
services for the VRID but do not have a real IP
address matching the VRID.
Default See page...
None 21-4
21-12
21-13
Not configurable 21-3
No authentication 21-5
21-14
VRRP – The Owner is 21-15
always the router that
has the real IP address
used by the VRID. All
other routers for the
VRID are Backups.
VRRPE – All routers
for the VRID are
Backups.
