Thank you for your information.<br>
So if I would like to have IP Address vprn interface SR-1 is 10.212.33.1 and IP Address vprn interface SR-2 is 10.212.33.2 and IP Address of Virtual Interface VRRP is 10.212.33.3 than the config should be :<br>
<div class="im"><br>
7750 SR-1:<br>
interface "test" create<br>
address <a href="http://10.212.33.1/25" target="_blank">10.212.33.1/25</a><br>
vrrp 10<br>
backup 10.212.33.3<br>
</div><div class="im"> ping-reply<br>
telnet-reply<br>
ssh-reply<br>
exit<br>
<br>
7750 SR-2 :<br>
interface "test" create<br>

backup 10.212.33.3<br>
priority 200<br>
ping-reply<br>
telnet-reply<br>
ssh-reply<br>
exit<br>

</div>Does my config can fulfill the requirement if the Virtual IP VRRP of 10.212.33.3 ?<br>
Thank you<br>

Also only one router should ever be master in each group. It's<br>
generally easier to configure the priorities differently so you know<br>
which one should be the primary.<br>
