OTV IMPLEMENTATION BETWEEN PRIMARY DC & SECONDARY DC

Dear colleagues ,

 

I have two data centres  to implement OTV using Cisco ASR1000 routers, I need  all the services/subnets that are currently in our Primary DC to be accessed/ replicated to the Secondary DC and Visa versa.

 

It's my first project and have never implemented this before so i need help on the design and configuration template for such a scenario   thanks so much

Hi @drabofred 

There is a configuration example here: https://www.cisco.com/c/en/us/support/docs/routers/asr-1000-series-aggregation-services-routers/117158-configure-otv-00.html

However, I would strongly encourage you to look for a more modern alternative to OTV as a DCI technology. More specifically to VXLAN.

OTV is great, don't get me wrong, but it has lots of limitations, and is quite old. VXLAN on the other hand is a much better choise.

 

Good luck,

Sergiu

Thanks so much for your feedback.

What requirements do I need to have in place if I am to implement VXLAN
,the two DC are 80km apart.
can you you share any guide for VXLAN implementation thanks

You do not need VXLAN, you can use OTV to extend the OTV VLAN across DC. (if you want you can do VXLAN, but when OTV can solve the problem you do not need VXLAN).
