IPv6 addresses on Cisco subinterfaces.. possible?
![[us]](/s/countries/us.gif) Shadow Hawkins on Friday, 20 July 2007 04:39:26
Has anyone successfully configured a static IPv6 address on a Cisco FastEthernet sub-interface and with a host on the same segment with a static IP address? I understand about the stateless autoconfig, but was just a test thinking I was not able to get the stateless autoconfig working on the host; however, I was able to get it to work on the actual Ethernet interface; (eth0/1 rather then eth0/1.1) statically and stateless autoconfig, this is how I am writing this thread. I suppose I will have to leave the configuration on Fasteth0/1 until I can figure out if this is a bug or by design.
Thanks

I suppose this new thread should have gone under IPv6 Setup; at any rate sorry for the ignorance on my part!!
IPv6 addresses on Cisco subinterfaces.. possible?
from Gert Doering:
"There are lots of different types of subinterfaces in Cisco, so this is a bit vague, if he's talking about 802.1q subinterfaces ("int eth0/1.50 ; encaps dot1q 50 ; ipv6 address...") this is Just No Problem, and has never been.
if you omit the "encaps dot1q" part, you can do subinterfaces, but you cannot configure IPv4 or IPv6 on them (I'm not sure what those are good for, then)"

Interesting... I was certainly referring to Cisco subinterface encap of ARPA.
I have always used Subinterfaces for 802.1q and never have tried encap ARPA and assign an IPv4 address on a subinterface, I have always assigned a seccondary IP on the primary interface; however, now that I try and assign a IPv4 IP to a Subinterface:
edge01(config-subif)#ip address 100.100.1.1 255.255.255.0
% Configuring IP routing on a LAN subinterface is only allowed if that
subinterface is already configured as part of an IEEE 802.10, IEEE 802.1Q,
or ISL vLAN.
and when assigning a IPv6 address:
edge01(config-subif)#ipv6 address 2001:4830:1700::3/64
edge01(config-subif)#
So I guess it is by design
I learn something new everyday!!
Thanks Jeroen.
