Minimum config for CSS for box-to-box redundancy

Answered Question

we have two CSS units CSS1 and CSS2. both have config wiped out clean. I have x-over cable patched between two units on interface "e1" on vlan 1 (VRRP vlan)

CSS1 will have 10.0.0.2/24 on circuit vlan1; CSS2 will have 10.0.0.1/24 on circuit vlan1. CSS1 should be Master with higher IP.

I want to get box-to-box redundancy operational before I add any content/service, then any new config is only needed on master unit then gets pushed to backup unit.

So what config will be added on both CSS to get basic redundancy up and working?

CSS1:

ip redundancy

interface e1

bridge vlan 1

circuit vlan1

ip add 10.0.0.2 255.255.255.0

redundancy-protocol

app

app session 10.0.0.1

CSS2:

ip redundancy

interface e1

bridge vlan 1

circuit vlan1

ip add 10.0.0.1 255.255.255.0

redundancy-protocol

app

app session 10.0.0.2

is it all? or need to configure other circuit vlan?

thanks a lot!

I have this problem too.

Hi,

when configuring redundancy, you can use following command:

ip redundancy master

on the CSS that you want to become the master. This way, the master also preempts, when it goes offline and comes back, it retakes the master role.

HTH,

Dario
