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.

• 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.

• 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.
