can EXOS or VSP (7432CQ version 8.9.0.0) do L2VSN in active/backup mode?

Hi all,

I am wondering if anyone here has experience with the following situation.

I have one subnet /30, one side on cpe, another side i want to use two PE routers which will use the same IP but in mode active / backup to form a link point-to-point with redundancy.

Like in a classical network, we can do l2vpn (or called xc, vpls, pw?), when the primary link goes down, they automatically switch to backup link.

Thx!

Hello,

With EXOS device, you can use do a "redundant" link with actif/passif mode. more information with link below.

hello Théo,

thank you for your message at first. LACP can't solve my problem here. i would like an equivalent of Pseudowire Redundancy (PWR) like cisco do.
