Table 12.1: VRRP and VRRPE Parameters (Continued)

Parameter

Description

Default

See page...

 

 

 

 

Virtual Router IP

This is the address you are backing up.

None

12-4

address

No default.

 

12-12

 

 

 

• VRRP – The virtual router IP address must be a

 

12-13

 

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.

 

 

 

 

 

 

VRID MAC

The source MAC address in VRRP or VRRPE

Not configurable

12-3

address

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>. 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.

 

 

 

 

 

 

Authentication

The type of authentication the VRRP or VRRPE

No authentication

12-5

type

routers use to validate VRRP or VRRPE packets.

 

12-14

 

The authentication type must match the

 

 

 

 

 

authentication type the VRID’s port uses with other

 

 

 

routing protocols such as OSPF.

 

 

 

• 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.

 

 

 

Note: MD5 is not supported by VRRP or VRRPE.

 

 

 

 

 

 

Router type

Whether the router is an Owner or a Backup.

VRRP – The Owner is

12-15

 

• Owner (VRRP only) – The router on which the

always the router that

 

 

has the real IP address

 

 

real IP address used by the VRID is configured.

 

 

used by the VRID. All

 

 

 

 

 

• Backup – Routers that can provide routing

other routers for the

 

 

services for the VRID but do not have a real IP

VRID are Backups.

 

 

address matching the VRID.

VRRPE – All routers

 

 

 

 

 

 

for the VRID are

 

 

 

Backups.
