>From my experience when we were running hybrid (catOS 6.5)(2x
Sup1a/MSFC2/PFC) Layer 2 was under 30 seconds and Layer 3 took a long
time, Probably close to 2-4 minutes.  Our FlexWAN had to start from
scratch, building interfaces and getting routing tables.  When we moved
to SRM the layer 3 time came down but can't remember what kind of time
it was.  We moved to Native so my memory may be a little fuzzy.

Can anyone comment on what the normal time would be for a 
Active->Standby Sup1A
switchover on a 6500?  I was looking on Cisco's site, and saw that they 
  did say for RPR it was
like 2-4 minutes and for RPR+ 30-60 seconds.  But it looked like RPR 
was a IOS feature,
and I am running Hybrid (6.4.3).  I realize that after the Sup 
switches, spanning tree has to
reconverge.  High Availability is enabled.
