VRRP-E differences for basic configuration
If you were to configure the two routers shown in
on page 534, you must consider the
following items specific to VRRP-E:
•
Specifying the <vrrp> 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 <vrrpe> node instead of
the <vrrp> node.
<vrrpe xmlns="urn:brocade.com:mgmt:brocade-vrrp">
<vrid>1</vrid>
<virtual-ip>
<virtual-ipaddr>192.56.7.25</virtual-ipaddr>
</virtual-ip>
</vrrpe>
•
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 <vrrpe> node.
<vrrpe xmlns="urn:brocade.com:mgmt:brocade-vrrp">
<priority>110</priority>
<vrid>1</vrid>
<virtual-ip>
<virtual-ipaddr>192.56.7.25</virtual-ipaddr>
</virtual-ip>
</vrrpe>
•
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.
