Question about redundancy between SM-SRE in two routers

[gwhuang5398]

I have two 2921 routers at the remote site, each has a SM-SRE-700 module installed to run WAAS. Is it possible to have redundancy between the two modules in two routers? how to have the two modules form a farm wit each 2921 router?

I also have a large site with two ASR1002 routers, each connects to a WAE-7341 appliance. Is there anything I need to be aware in particular betwen ASR and WAE configurations? I looked up Cisco documents but didn't find right information. Can I just use the general configuration on the ASR routers as other ISR routers?

Thanks a lot

Hi Gary

Technically as far as IP reachability is there among the routers and SREs, they should be able to form a farm. Also hope you aware that this solution won't be able to give the same redundancy as isolated platforms, ie: when router fails, SRE also goes down. However I'll let other experts to comment on their recomendation on this..

Following document is a good one to understand WCCP on ASR100) which is the key area you need to focus when integrating with WAAS
