EoMPLSoGRE using ASR 1000

[muthumohan]

Hi All,

I need to extend Layer 2 between two Data Centers over IP cloud. I am looking at the EoMPLSoGRE option and wondering which ASR I need to buy to have this feature working. Will basic model of ASR 1000 do? Or, do we have to buy any specific model of ASR ( and SPAs) for this EoMPLSoGRE to be working. Any specific version of IOS needed for this feature?

As of now, we have L3 MPLS VPN between the sites, terminated on Cisco 3900 series routers. We want to use this IP cloud to build this L2 extension just temporaily for migrating some servers where we cannot change the IP address of the servers due to application complexities.

Any help is hightly appreciated. Also, if you can point me to a sample setup and configuration for EoMPLSoGRE, it would be of great help.

Thanks and Regards,

Mohan Muthu

Any ASR Model running IOS XE 2.4+ supports ATOM Over GRE, i would recommend you to read this document in detail, and tell us if you need any further help.

Hello Mohan,

I would recommend you to use the Feature Navigator tool at the Cisco site

www.cisco.com/go/fn

There you'll be able to look for any feature support on whatever platform/IOS/feature set.

Thank you All for your help.

I have decided to use L2TPv3 for extending the VLANs across the IP backbone. I will have Cisco 3660 at one end and Cisco 3945 on the other end. I have also checked on the Feature Navigator that a version of IOS supports L2TPv3 on them. Anything else I should look for ?

Thank you,

Mohan
