Hello,
I'm trying to configure IPv6 on a Cisco 877W. According to all documents I can find via Google both the hardware and the IOS (12.4(4)T4 in this case) should support IPv6. But the machine doesn't know the "ipv6" command nevertheless.
What am I doing wrong?
Kind regards
in conf mode he doesn't know "ipv6 unicast-routing"? you have to enter this first before you can give ipv6 addresses to interfaces
arne
No, I already tried that. It doesn't accept the command:
jumpgate(config)#ipv6 unicast-routing ^ % Invalid input detected at '^' marker.
Kind regards
Hi Matthias,
You may wish to investigate the Cisco 877W Config Wizard:

I found out my my 877W doesn't support IPv6 in the meantime: Despite the fact that the dealer who sold the Cisco to me lists "IPv6 support" as one of the features it is included in IOS image. The Cisco 877W-G-E-K9 only provides "Advanced Security Options" but not "Advanced IP Services" by default.
"Advanced IP Services" can be purchased seperately and requires a larger flash memory.
Kind regards
I think that you will find that the image itself will fit in the flash. Perhaps if you need to keep the SDM (web interface) files then there may be a problem. If you don't want the SDM files you can just delete them.
If the image fits in the flash it will work.
System image file is "flash:c870-advipservicesk9-mz.124-4.T1.bin"
ipv6 unicast-routing ipv6 cef ipv6 dhcp pool ipv6-dhcp etc
It works fro me with this IOS version.....
