VRRP and VRRPE parameters
31
VRID MAC
address The source MAC address in VRRP or VRRPE 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.
Not configurable page 1103
Authentication
type The type of authentication the VRRP or VRRPE routers use
to validate VRRP or VRRPE packets. The authentication
type must match the authentication type the VRID 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.
No authentication page 1106
page 1115
Router type Whether the router is an Owner or a Backup.
•
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.
VRRP – The Owner is
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. page 1116
Backup priority A numeric value that determines a Backup preferability
for becoming the Master for the VRID. During negotiation,
the router with the highest priority becomes the Master.
•
VRRP – The Owner has the highest priority (255);
other routers can have a priority from 3 – 254.
•
VRRPE – All routers are Backups and have the same
priority by default.
If two or more Backups are tied with the highest priority,
the Backup interface with the highest IP address
becomes the Master for the VRID.
VRRP – 255 for the
Owner; 100 for each
Backup
VRRPE – 100 for all
Backups page 1116
Suppression of
RIP
advertisements A router that is running RIP normally advertises routes to
a backed up VRID even when the router is not currently
the active router for the VRID. Suppression of these
advertisements helps ensure that other routers do not
receive invalid route paths for the VRID. Disabled page 1117
Hello interval The number of seconds between Hello messages from
the Master to the Backups for a given VRID. The interval
can from 1 – 84 seconds. One second page 1105
