Now I use HSRP for 6000 MSFC but someone suggests me to change it to SRM. Do you have any idea about this?

Single Router Mode (SRM) is a new feature that addresses the drawback of the previous HSRP based redundancy scheme.

Each has its own pros and cons. Take a decision weighing each of them against others
Dual MSFC with HSRP
---------------------------
* Need more IP addresses (HSRP)
* If you are using Flex WAN interface, they can be controlled only by the DR
* HSRP Convergence will be faster than SRM mode
* Effective usage of MSFC resource as load sharing is possible
SRM
-----------
* One IP address is sufficient. no HSRP is required.
* No stateful failover is supported yet. So convergence will depend on RP and other process to initialise
* FlexWAN configuration is simple. They are always attached to either of the MSFC. So no manual config required
* Load sharing is not possible. At a given time, only one SUP/MSFC is used.The other one is dormant waiting to take over if the active one fails
Hope this helps
