To create a virtual routing cluster using EdgeRouters (or any router that supports the protocol). The idea is that each router will have an interface IP and a shared virtual IP.<br />
<br />
*R1 ETH0 -> 192.168.0.2<br />
*R2 ETH0 -> 192.168.0.3<br />
*VirtualIP -> 192.168.0.1<br />
<br />
ssh into router 1 and use the following commands<br />
Replace the "X" with your environment's variables.<br />
<br />
configure<br />
set interfaces ethernet ethX vrrp vrrp-group XXX virtual-address XXX.XXX.XXX.XXX/XX<br />
commit;save;exit<br />
<br />
Then the same thing in the router2.<br />
<br />
configure<br />
set interfaces ethernet ethX vrrp vrrp-group XXX virtual-address XXX.XXX.XXX.XXX/XX<br />
commit;save;exit<br />
<br />
If both routers are on the same switch, they will work out who is master and who is backup. To designate this manually use the following commands on R1<br />
set interfaces ethernet ethX vrrp vrrp-group XXX priority XXX<br />
commit;save;exit<br />
(NOTE: The priority numbers range from 1-254, the higher the number the higher the priority)<br />
On R2<br />
set interfaces ethernet ethX vrrp vrrp-group XXX priority XX<br />
commit;save;exit<br />
In the event the master router goes down, the backup is running, and you don't want them to switch when the master comes back online; disable preemption on both routers.<br />
set interfaces ethernet ethX vrrp vrrp-group XXX preempt false<br />
commit;save;exit<br />
To secure the routing cluster from an unauthorized router joining them<br />
set interfaces ethernet ethX vrrp vrrp-group XXX authentication type ah<br />
set interfaces ethernet ethX vrrp vrrp-group XXX authentication password ??????????</div>Michael.mast
