[c-nsp] Distance limit of ASA Failover

[Chris Kane]

I've been looking for some doco and was hoping someone here had a good
reference. Now that so many of us are extended Layer 2 between data centers
I'd like to find documentation that recommends the distance limit for the
ASA Failover. Since pseudowires hide the Ethernet distance I'm wondering if
there is a time based limitation (ex. 30ms). And I'm assuming only
Active/Standby could be supported in geographically distant (read several
hundred miles apart) data centers.

Thanks,
