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!

Hi, for b2b configuration, take a look of the following links:

and Box-to-Box Redundancy on the CSS 11xxx Configuration Example:

thanks a lot!
I am kind of confused by which CSS will become Master based on IP address on the fail-over link.
if both units come up at the same time, the one with higher IP (on failover link) will be the master?

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.
