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

7750 SR-1:



            interface "test" create

                address 10.212.33.1/25

                vrrp 10

                    backup 10.212.33.3

                    priority 200

                    ping-reply

                    telnet-reply

                    ssh-reply

                exit

                vrrp 20

------------------ >backup 10.212.33.4

                    ping-reply

                    telnet-reply

                    ssh-reply

                exit





7750 SR-2 :



            interface "test" create

                address 10.212.33.2/25

                vrrp 10

                    backup 10.212.33.3



                    ping-reply

                    telnet-reply

                    ssh-reply

                exit

                vrrp 20

----------------- >backup 10.212.33.4
----------------- >priority 200

                    ping-reply

                    telnet-reply

                    ssh-reply

                exit
