Pinging an IPv6 Address on a cable interface on a CMTS

[surfbum99]

Hi,

I've got a interface bundle config of the following using a uBR VXR 7246:

interface Bundle1
ip address 192.168.24.1 255.255.255.0
ip pim sparse-mode
cable arp filter request-send 3 2
cable arp filter reply-accept 3 2
cable dhcp-giaddr primary
cable helper-address 192.168.4.222
ipv6 address 2001:558:FF10:806::/64 eui-64
ipv6 address 2001:558:FF10:80D::/64 eui-64
ipv6 enable
ipv6 nd prefix 2001:558:FF10:806::/64 60 30 no-autoconfig
ipv6 nd prefix 2001:558:FF10:80D::/64 60 30 no-autoconfig
ipv6 nd managed-config-flag
ipv6 nd other-config-flag
ipv6 nd ra interval 5
ipv6 nd ra lifetime 30

But I was wondering how do I think ping the cable interface on the CMTS :

vxr7246#ping ipv6 2001:558:FF10:806::

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2001:558:FF10:806::, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)

The reason behind your no reply is you are not finishing the IP.

2001:558:FF10:806:: is your prefix. What is the default gateway?

As you see in your config you have a eui-64 this means that the IP that you want on the interface is the perfix and your MAC plus FFEE inserted in the middle of you MAC to get it from 48 bit to 64 bit.

Issue a sh ipv6 int brie command and then ping that address that will be your local address.
