DHCPv6 on Cisco 881

Answered Question
Feb 9th, 2012

Hi Guys

I am not able to activate DHCPv6 on my Cisco Router 881 (Version 15.2(2)T). There is no ipv6 dhcp ... in global config mode.

Cisco feature navigator tells me there is dhcpv6..

Router(config)#ipv6 unicast-routing

Router(config)#ipv6 cef

Router(config)#ipv6 ?

  access-list      Configure access lists

  cef                        Cisco Express Forwarding for IPv6

  flowset               Set flow label random for originated packets

  general-prefix   Configure a general IPv6 prefix

  hop-limit        Configure hop count limit

  host             Configure static hostnames

  icmp             Configure ICMP parameters

  inspect          Context-based Access Control Engine

  local            Specify local options

  nat              NAT-PT Configuration commands

  nd               Configure IPv6 ND

  neighbor         Neighbor

  port-map         Port to application mapping (PAM) configuration commands

  prefix-list      Build a prefix list

  radius           RADIUS configuration commands

  route            Configure static routes

  router           Enable an IPV6 routing process

  source-route     Process packets with source routing header options

  spd              Selective Packet Discard (SPD)

  tacacs           TACACS configuration commands

  traffic          Configure traffic parameters

What's wrong with my box?

Currently, the DHCPv6 server is only available in the Advanced IP services feature on the 800 series platform.

Here is the data sheet for feature to license mapping:

I don't know if there are any plans in the future to change it, but what you are seeing today is the expected and intended behavior.

I think you have some issues with your IOS licensing.

You are probably right.

Are you trying to be an DHCPv6 client or a DHCPv6 server?

DHCPv6 client is an interface subcommand, not a global one.  It is activated on an interface by interface basis.

http://www.cisco.com/en/US/docs/ios/ipv6/configuration/guide/ip6-dhcp.html#wp1054391

DHCPv6 server is in the same license set as DHCP server (IPv4 and IPv6 should be at feature parity), so based on Feature Navigator it looks like you would need Advanced IP Services or Advanced Security license.  And you have Advanced Security.

Could be a license issue, you might want to open a TAC case.

OK, some internal experiementation indicates that in the version you run, the DHCPv6 server is available in the Advanced IP Services feature set.  You are running the Advanced Security feature set.

It is not clear to me if this state of licensing is intentional or an oversight.  I am researching that now.  Typically, Cisco products maintain parity between IPv4 and IPv6 features within a feature set.

In the interim, you should install an evaluation license for Advanced IP Services (advipservices) to activate the DHCPv6 server.

Thanks for the update Phillip. Is there any way we can feed this back to Cisco? It seems an unusual decision to omit DHCPv6 from the Advanced Security feature set. Especially on branch-office devices like these.

Phillip Remaker Thu, 06/14/2012 - 07:49

The 800 series product manager has been alerted and understands the problem, but they curently have no committed time frame to fix it.  I'll update this thread if I learn any more from them.  I also recommend filing a complaint through your sales channel and encouraging your peers with a similar issue to do the same.  Work prioritization is ultimalely driven by customer sentiment.

Hi . Any progress with problem of DHCP6 server on 88x series ?  Situation really bad because RFC 6106 also not supported by cisco . So not have another way to configure ipv6 connectivity. I am little bit wondered why such feature implemented only in ADV IP.
