ISR 4331 inter-chassis high availability

[jay3]

Hi Friends,

I need assistance with understanding and setting up inter-chassis high availability.I have two routers that I want to set-up in active/standby and I came across that technology in my research.The two routers I want to set-up will be located at the WAN edge and will be used to inter-connect my branches using dynamic routing.Thanks in advance

Hello,

there are certain restrictions and prerequisites with regard to inter-chassis HA, other than that, the configuration is fairly straight forward. 

I am not sure how far you have gotten in your research, but the link below has step by step configuration details...

What Georg describes might be more than you're asking about. You're just asking a how to use a FHRP (e.g. HSRP) with dynamic routing?
