[carl_townshend]

Hi All

Has anyone got a basic config to get OTV working between 2 ASR switches?

I have 10 vlans 1-10 I would like to get across to the other side.

what would the config look like

cheers

Are people still using OTV, or is VXLAN-EVPN the way to go these days for DCI ?

Hi,

    This is a.....long discussion.It really depends on what exactly you're trying to achieve, how complex and redundant your design is, you can't just flip a coin, as on the long run you could run into issues. Assuming HW and knowledge of implementation and support is not a problem, it really foes down to current and future architecture you want to reach.
