Layer 2 MPLS VPN Configuration

[Subin Kallidumpil]

Hi Team,

I working on the scenario as shown above.

We have two link's (Layer 2 MPLS VPN) from two different service provider (Bhaarti and Tata).

I would like to configure port channel between the sites 1 and 2 respectively and this will be trunk links.

Just wanted to confirm whether this possible. If yes, can some one provide me with a configuration example.

Regards

Hello Subin,

the recommended practice is to use LACP for having a protocol that exchanges messages over each member link.

However, you need to test because not all MPLS L2 VPN services are equal and not all of them allow LACP messages to be exchanged.

On your devices you need to configure a bundle using

interface type x/y

channel-group N mode active

the same group N has to be used on the ports of the same switch.

You can find a free unused bundle number by looking at

show etherchannel summary

possible values for the bundle number are platform dependent.

If both service providers transport LACP frames over their own network  you are fine.

Hope to help

Giuseppe
