Replacing VPLS with EVPN in multi-BNG architecture – is it possible?

  • 1.  Replacing VPLS with EVPN in multi-BNG architecture – is it possible?

    Posted 22 days ago

    Hi everyone,

    I'd like to know if it's possible to configure a scenario with multiple BNGs connecting to a PE using EVPN instead of VPLS.

    Here's my current setup: each BNG has a ps900 interface where subscribers connect. This interface is transported via l2ckt to a PE router, which has a VPLS instance to interconnect all the BNGs through this VLAN.

    Now, I'm looking to migrate or redesign this setup using EVPN on Junos. Is it possible to implement something similar with EVPN, and if so, how would the design look?
    I tested EVPN-VPWS as suggested in the documentation, but it doesn't suit this case, since the BNGs operate in parallel. I'd like to maintain a forwarding table that allows subscribers to reach any of the BNGs, with PPPoE sessions automatically balanced depending on which BNG responds.

    Has anyone tried something like this or can share some guidance?

    Thanks in advance!
