Requesting IPv6 DHCP-PD Prefix Size

[WarEagleX]

I am able to get an ipv6 /64 address from Xfinity with no problem however I have multiple subnets I need to cover with ipv6 so I'll need a /60 or lower.  How do you specify the DHCP-PD request for a /60 in the RV340 so that I can break up into a multiple /64?

There's plenty of information on how to do it in the cli on a regular router but nothing on the 340 GUI.

Thanks in advance and WAR EAGLE.

Hello,

I think with IPv6 rapid deployment you can specify the prefix/length (see page 44 of the atrached user guide)...

Rapid Deployment requires an ipv6 tunnel.  I have this up and running with HE and they allow you to select a /48 from their interface.  This works perfectly.  Xfinity, on the other hand, has no such portal so they rely on the hint command for the client to ask for a block lower than a /64.  

Traditional Cisco routers enable the following hint command in the Interface configuration:

ipv6 dhcp client pd hint

I'm trying to understand how to do this on the RV340.  Its the only way to request a /60 from Xfinity.

Make sense?

Makes sense...

Your options regarding prefix delegation on the RV340 are very limited. The only PD related option you have is to specify a prefix name (page 37 step 8 of the attached user guide)...
