What do you think about migrating the 6500 to native IOS? Perhaps, it maybe
the best solution

Asunto: RE: 6500 Flexwan modules & Msfc
As I said it depends on your requirements. Using SRM you only have one
active router and therefore you cannot load balance. Also fail over time is
greater than with HSRP on the VLANS.

What you really need to do is run the MSFC's in SRM, single router
mode. This way you will have automatic redundancy if the case of an
MSFC failure. Otherwise if you loose your MSFC that controlls the
flexwan you will have to manually configure your second MSFC, not a good
plan.
