Juniper MX BNG Static IPv6 Prefix

3 weeks ago

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
