Gateway Redundancy between 2 VSS Domains

Unanswered Question
Oct 8th, 2009

Hi Everybody,

I'm interested in hearing your opinions about the best way to deploy gateway redundancy between 2 VSS Domains.

With HSRP works fine, but i wish to know if there another best way.



I have this problem too.

You can use layer 3 links between the pairs of the VSS's and let the IGP control it. This will provide multiple paths and you can load balance and increase the bandwidth between the two.

Wow. How much redundancy does one need. Two VSS domains :-)

AS far as i know, from the moment you have more than one VSS domain, this will again introduce HSRP or any other FHRP in your config.

Yeah, i don't know any other way...

That redundancy is because there are two datacenters connected through L2 links...

Each VSS domain is in one datacenter, so, to have gateway redundancy, i used HSRP.
