  1. Hi Anton,
    Does PWHE support any type of redundancy? what if one BNG fails and you need to terminate subscriber to different BNG?
    thank

    1. Hi Tim,
      The topic redundancy is very interesting and there are numerous option how you can achieve the result. Basicaly VPWS has built in mechanism for redunandcy via configuration of backup peer inside PW. Another option would be configuration of several BNGs with the same IP address fo customer termination and usage of HA/clustering or anycast IP.
      BR,
