Just unbundled some new kit from Cisco, an ISR 4331..
Cisco IOS XE Software, Version 03.13.02.S - Extended Support Release
Cisco IOS Software, ISR Software (X86_64_LINUX_IOSD-UNIVERSALK9-M), Version 15.4(3)S2, RELEASE SOFTWARE (fc3)
It accepted all of my previous ipv6 commands from the old router except for: ipv6 dhcp client pd IPV6-PD
Basically it doesn't exist in interface configuration anymore... I can't find any documentation on it either. This is all the options I get..
Router(config-if)#ipv6 dhcp ?
framed Framed-IPv6-Prefix allocation
relay Act as an IPv6 DHCP relay agent
server Act as an IPv6 DHCP server
Cheers,
Jordan.
