Migrating from Cisco 2911 to ISR 4321

[Arpit_]

We're migrating from Cisco 2911 Router to Cisco ISR 4321 Router.

2911 Configuration:

--> 2 WAN 10Ge Ports, 1 is Assigned to WAN & 2nd is Assigned to Internal Network with Sub-Interfaces.

--> EIGRP Routing connecting to other sites via Multipoint GRE Tunnel over IPSec

--> NHRP

--> GRE Tunnel for Multipoint Operation

Are there in recommendations for migrating to Cisco ISR 4321 ? How configuration needs to be migrated ? Does it needs to be configured from Scratch ?

I'm adding the router configuration of Cisco 2911 Below. Any recommendation will be appreciated.

Thank You

Hi

I'm reading it quickly through myself iPhone and you have basic config.

You can migrate ask except boot image command and self signed certificate.

Just a recommendation: use something higher than group 2. I don't know if your isakmp key is the same across all nodes but if it is, you can use isakmp profile to avoid multiple lines.
