[alcatel-nsp] VRRP for VPRN on 7750

[Andhy Indarto]

Dear all,

I have config the vprn with vrrp feature. The config looks like this :

 

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 10.212.33.2

                    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

                    priority 200

                    ping-reply

                    telnet-reply

                    ssh-reply

                exit

                vrrp 20

                    backup 10.212.33.1

                    ping-reply

                    telnet-reply

                    ssh-reply         

                exit

 

and the verification with show command are :

 

7750 SR-1 :

 

7750_SR1# show router 400 vrrp instance

The result is when the condition of vrrp is master and master than the
traffic flow is normal such as in interface "test1" but when the
condition of vrrp is master and backup than the traffic flow is fail.

What is the good condition or the default condition of vrrp ? is it
master and backup or master and master ?

Is there any miss configuration that I make ?

For service redundancy, especially vprn, does it better use vrrp or srrp
?

Thank you for the support.
