ASR -Adaptive session Redundancy on CSS11503

Recently we brought CSS11503 one master and other configured as Backup using redundant vips.

now i m planning to impliment ASR on these.

I found a doc on cisco site

http://www.cisco.com/en/US/partner/products/hw/contnetw/ps792/products_configuration_guide_chapter09186a00801186e9.html#1015654

At the last page it give a sample config of ASR.

but the sample has only on service.

and In our production environment we have n services and its not allowing me to configure same redundant-index for all the services.

Any ideas ??

Re: ASR -Adaptive session Redundancy on CSS11503

For Adaptive Session Redundancy, you're probably looking for this section of the documentation:

http://www.cisco.com/en/US/partner/products/hw/contnetw/ps792/products_configuration_guide_chapter09186a00801186ec.html#1043738

Basically, each service will require a unique redundant-index, and the services and redundant indexes need to match across both CSS's.

now my question is what is the redudant-index # should i give for the content rule and group???

Re: ASR -Adaptive session Redundancy on CSS11503

Redundant indexes need to be unique within services, content rules, and groups. So you could start again at 1 for your content rules, and start again at 1 for your source groups. You just can't reuse an index *within* the entities.

Don't forget to also assign an isc-port on each (perhaps a redundant isc port also) switch and connect the cable.
