Enabling preemption

The procedure for enabling pre-emption differs depending on the Ethernet link interface type,
which for VRRP can be a physical Ethernet link (10 Gigabit Ethernet, Gigabit Ethernet, 40 Gigabit
Ethernet), port-channel, or VE. For VRRP-E, the Ethernet link interface type must be VE.

Enabling preemption for physical Ethernet or port-channel

To enable preemption for a physical or port-channel router interface, perform the following steps.

1. Issue the <edit-config> RPC to configure the <interface> node in the

urn:brocade.com:mgmt:brocade-interface namespace.

2. Under the <interface> node, specify the <gigabitethernet>, <tengigabitethernet>,

<fortygigabitethernet>, <hundredgigabitethernet>, or <port-channel> node, depending on the
Ethernet link interface type.

3. Under the <gigabitethernet>, <tengigabitethernet>, <fortygigabitethernet>,

<hundredgigabitethernet>, or <port-channel> node, include the <name> element and specify
the name of the backup router interface.

4. Under the <gigabitethernet>, <tengigabitethernet>, <fortygigabitethernet>,

<hundredgigabitethernet>, or <port-channel> node, include the <vrrp> node element located
in the urn:brocade.com:mgmt:brocade-vrrp namespace.

5. Under the <vrrp> node, include the following leaf elements.

a. In the <vrid> element, specify the group ID of the VRRP router group.

b. Include the empty <preempt-mode> element to enable preemption.

The following example enables preemption.

<?xml version="1.0" encoding="UTF-8"?>

<edit-config>

</target>

<preempt-mode/>

</vrrp>

</tengigabitethernet>

</interface>

</config>

</edit-config>

</rpc>

<rpc-reply message-id="3502" xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">

<ok/>

</rpc-reply>
