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?
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
