CSS failover

[g.raymakers]

I'm planning to put one CSS 11503 at siteA and another one at siteB. Both sites are connected with mutiple Gbps connections with low latency e.g. <0,5msec. Is there a distance limition for having the Adaptive session redundancy feature running between 2 CSS's?

I believe it is up to 10km if you have the correct fiber to support it.

However, be aware that we officially do not support ASR with intermediate L2 devices between the CSS.

Thanks. However is there a Cisco approved solution for this?

[Gilles Dufour]

no.

If you have distant sites, the solution is GSLB with ASR at each location.
