High Availability interchasis redundancy feature

Hi all,

     Do ISR 4331 supports High Availability interchasis feature ,second is if i am using ISR 4331 for that what will be the physical connectivity ?

Like this :

                   ----------------     ISR 1

Router____-____             

 ISP            -----------------    ISR 2

Please suggest do i need to connected Router ISP to both of the ISR 1 and ISR 2 or there any other way to do it ?

The 4331 does not support any

The 4331 does not support any form of dedicated inter-chassis link - however it is likely to be able to meet any HA requirement you have.

However there is not enough detail in your question to give you any guidance.  If I understand, you have a single link from the ISP and the ISP has a single router.  Has the ISP given you a block of IPv4 public address space, or will everything be nat'd?

Will the ISP give you two ports on their router to plug your two routers into?
