Hi , We have a serial link with Crypto configured.

Not Telcom wants to change the interface to Etherenet.

There is G0/0 interface . They said new link is MPLS.

Diginet to EThernet .

 Please advise about crypto config . can I use the same Crypto

Current Int

interface Serial0/1/1

Hello sudheerkumar9@hotmail.com ,

you can use the same crypto map if the local subnets and remote subnets are the same.

The crypto map does not depend on the type of interface used.

Hope to help

Thank You . We will implement the change later 1fter 4 Hrs. WIll update the status .
Also this crypto is not active now as the Source ip interface is shut down as backup site.https://community.cisco.com/t5/forums/replypage/board-id/5981-discussions-other-network-infra/message-id/200534
Can we create a loopback with source Ip and ping remote to test the crypto active ?

Hi,

You can create loopback IP for testing make sure to allow test source and destination IP address in proxy ACL in site A and B. Ensure also that you have a route between your test source and destination which sometimes neglected preventing successful ping.
