Vrrp And Vrrpe Parameters - Dell PowerConnect B-RX Configuration Manual

VRRP and VRRPE parameters

Router1 is the master for VRID 1 (backup priority = 110) and Router2 is the backup for VRID 1
(backup priority = 100). Router1 and Router2 both track the uplinks to the Internet. If an uplink
failure occurs on Router1, its backup priority is decremented by 20 (track priority = 20), so that all
traffic destined to the Internet is sent through Router2 instead.
Similarly, Router2 is the master for VRID 2 (backup priority = 110) and Router1 is the backup for
VRID 2 (backup priority = 100). Router1 and Router2 are both tracking the uplinks to the Internet.
If an uplink failure occurs on Router2, its backup priority is decremented by 20 (track priority = 20),
so that all traffic destined to the internet is sent through Router1 instead.
The device configured for VRRPE can interoperate only with other device.

TABLE 84
VRRP and VRRPE parameters
Parameter Description
Protocol The Virtual Router Redundancy Protocol (VRRP) based on RFC
2338 or VRRP-Extended, Brocade's enhanced implementation of
VRRP
VRRP or VRRPE The device's active participation as a VRRP or VRRPE router.
router Enabling the protocol does not activate the device for VRRP or
VRRPE. You must activate the device as a VRRP or VRRPE router
after you configure the VRRP or VRRPE parameters.
Virtual Router ID The ID of the virtual router you are creating by configuring multiple
(VRID) 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.
No default.
Virtual Router IP This is the address you are backing up.
address
No default.
•
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
subnet 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 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.
