VRRP-E differences for basic configuration

If you were to configure the two routers shown in

Figure 8

on page 534, you must consider the

following items specific to VRRP-E:

Specifying the element in the urn:brocade.com:mgmt:brocade-vrrp namespace enables
VRRP-E as well as VRRP.

VRRP-E virtual routers ca be configured on VE interfaces only.

VRRP and VRRP-E cannot be simultaneously enabled on the VDX 6740 or 6740T.

The group ID and the virtual router IP address are specified under the node instead of
the node.

1

192.56.7.25

Specification of the master router is done by giving the master a higher priority than the
backup router. The priority is also specified under the node.

110

192.56.7.25

For VRRP-E, you cannot assign the same IP address to the physical interface and to the virtual
router.

Enabling preemption

You can allow a backup router that is acting as the master to be preempted by another backup
router with a higher priority value.

By default, preemption is enabled for VRRP, or disabled for VRRP-E.

NOTE

If preemption is disabled for VRRP, the owner router is not affected because the owner router always
preempts the active master.
