vrrp high availability topology

Is there any procedure to add or remove an interface in vrrp high availability topology without cause fail-over?

Sure. First stop the standby member (or disconnect / shut down it's network interfaces) so that it cannot become active. Then remove the interface on the active and stopped standby member. Finally start the standby member again. Adjust the cluster topology within your SmartCenter as well and push policy.

Thank you for the reply

To stop the standby, is there an equivalent cmd like for clusterXL mode (clusterXL_admin up/down)?

Not that I know of. I'd simply use cpstop/cpstart.

On the backup gateway use the command:

set vrrp disable-all-virtual-routers on

Now make the changes you want, if you need to remove an interface from the list, first do it from the backup, then you don't need the above command either. Once your done just send the same command with off at the end.

Thanks all for your contributions

I was able to add a new interface without any issue. I used finally clusterXL_admin command

Just so you know, VRRP will only take notice of that state if FW monitor is on. set vrrp disable-all-virtual-routers will really make sure VRRP will be admin down and clusterXL_admin doen will only put that system in problem state not in down state.
