Junos OS

Dear All,

I have a question about the IPv6 PD for Junos Subscriber Management. Is there a way to get the subnet for the prefix delegation directly from the radius server without being forced to configure the pool locally on the MX router? That is, I don't want to get the pool name from the radius, but directly the subnet to be delegated.

Thanks in advance,

Nicola

Hi,

You can assign the DHCPv6 IAPD using below CLI.

labroot@jtac-mx960-r2032-re1# set system services dhcp-local-server dhcpv6 overrides delegated-pool ?
Possible completions:
<delegated-pool> Delegated pool name for inet6

Regards,
Rahul

Ok I misunderstood. You need assign IAPD address from radius rather than sending the pool name from radius.

Did you tried below radius attribute?

Using a AAA RADIUS Server to Obtain IPv6 Prefixes for Prefix Delegation

• Delegated-IPv6-Prefix—The attribute (123) contains an IPv6 prefix that the BNG can send to the CPE.

• Jnpr-IPv6-Delegated-Pool-Name—The attribute (VSA 26-161) contains the name of an address-assignment pool configured on the BNG from which the BNG can select a prefix to send to the CPE.

Both attributes are sent from the RADIUS server to the BNG in RADIUS Access-Accept messages.

Framed-IPv6-Prefix = 200X:X:XXX:X::/64,

Delegated-IPv6-Prefix = 200X:X:X::/56,

{master}

Thank you very much Mayar,

yes, that is what I was looking for, the "delegated ipv6 prefix" attribute should be supported by junos, I still need to try it but thank you for your prompt anser 🙂

Have a nice day!
