Issue Description

Product: NE40

Version: V600R008C10SPC300

 

Problem:

Was observed that was not received option-82 in DHCPv6 with information about which ONT is connected an IPv6.

 

 

I’ve asked about diagnostic information since we need to know the current status and software of the device and the output of the below commands:

 

display version

display patch-information

 


Solution

In DHCPv6, the option 82 has been replaced with options 18 and 37 as per RFC 3315 and RFC 4649

 

DHCPV6 interface-id (option 18) is the equivalent of DHCPv4 option 82.1 (circuit id)

DHCPv6 remote-id (option 37) is the equivalent of DHCPv4 option 82.2 (remote id)

 

On NE-40 the configuration is performed using the command dhcpv6 relay option-insert

This command is also part of the configuration example sent in the previous email.
