Juniper MX BNG Static IPv6 Prefix

  • 1.  Juniper MX BNG Static IPv6 Prefix

    Posted 10-06-2020 02:20

    Hi

    I am trying to assign static IPv6 Prefix to WAN side of CPE, so I used following AVP in RADIUS Profile:

    Framed-IPv6-Prefix = 2a02:30c0:2:d1::/64

    But when the subscriber is connected to BNG, It has two prefixes

    This configured Prefix and one Prefix from NDRA pool.

     

    jcluser@vMX1> show subscribers user-name 217625test4 extensive
    Type: PPPoE
    User Name: 217625test4
    IPv6 Prefix: 2a02:30c0:2:8025::/64
    IPV6 Primary DNS Address: 2001:4860:4860::8888
    IPV6 Secondary DNS Address: 2001:4860:4860::8844
    IPv6 User Prefix: 2a02:30c0:2:d1::/64
    The question is How can I tell the BNG to stop assigning A Prefix from POOL while it assign the Static IPv6 Prefix via RADIUS?

    Thank you
