how to implement VRRP with 5500

[Roland_1]

Hi everybody.

I need your help in implementing VRRP between two 5500G-EI.

I already have a 5500G-EI.

This switch is configured with layer 3 routing between 192.168.1.0 and 192.168.2.0

So it has 2 ip address on its vlan 1 interface with the .sub function.

Switch A

interface Vlan-interface1

 ip address 192.168.1.254 255.255.255.0

 ip address 192.168.2.254 255.255.255.0 sub

This switch is full functional and I use it for routing my 2 ip networks without vlans.

Now I want to add a second 5500G far from the first 5500G. (another bay)

Switch B

interface Vlan-interface1

 ip address 192.168.1.253 255.255.255.0

 ip address 192.168.2.253 255.255.255.0 sub

This new switch must backup the first one in it’s routing job.

To help in this job i want to implement VRRP.

The new virtual router ip is : 192.168.1.250 for the first interface vlan1.

The new virtual router ip is : 192.168.2.250 for the sub interface vlan1.

I don’t  know how to make it.

First solution : creating a unique vrid

Switch A

vrrp vrid 1 virtual-ip 192.168.1.250

 vrrp vrid 1 priority 110

vrrp vrid 1 virtual-ip 192.168.2.250

 vrrp vrid 1 priority 110

Switch B

vrrp vrid 1 virtual-ip 192.168.1.250

 vrrp vrid 1 priority 100

vrrp vrid 1 virtual-ip 192.168.2.250

 vrrp vrid 1 priority 100

Second solution : creating one vrid by interface

Switch A

vrrp vrid 1 virtual-ip 192.168.1.250

 vrrp vrid 1 priority 110

vrrp vrid 2 virtual-ip 192.168.2.250

 vrrp vrid 2 priority 110

Switch B

vrrp vrid 1 virtual-ip 192.168.1.250

 vrrp vrid 1 priority 100

vrrp vrid 2 virtual-ip 192.168.2.250

 vrrp vrid 2 priority 100

What do you think about this ?

Any comment appreciated

Thank’s

I think that the best option is to use a unique VRID, because two virtual IP addresses per interface VLAN doesn't make sense...VRRP is great to simplify the scenarios where you need backup routing instances or devices; so, I think that this is the best choice.

Hi,

in fact i already have this config running on one switch with 2 ip on the same interface vlan1.

This switch is actually routing lan 192.168.1.0 with 192.168.2.0. so it's ok  to have 2 ip address.

I just want to add another identical switch with similar routing function in case of harware failure.

The first solution is to configure the new second switch, unplug it and wait for the failure.

Then we have to unplug  the broken switch and plug the new.

The second solution, i mean, is to configure VRRP and use actively the two switches for switching.

Routing is done by vrrp on the first or the second switch depending on config.

Thank's for your help.

Hi Roland,

I have read your topic: How to implement VRRP with 5500 switch.

It is interesting.

I just graduarated. And I work to SI company. In the near future, I will work with 5500 switch.

I hope to study it from you.

You can present how to implement VRRP with 5500 switch better.

Thanks you very much.
