IPv6 and SMCD3G not recognising the PD address
I believe I have my Cisco router configured correctly via:
http://www.cisco.com/c/en/us/support/docs/ip/ip-version-6-ipv6/113141-DHCPv6-00.html and http://packetpushers.net/ipv6-home-prefix-delegation/ and http://networkengineering.stackexchange.com/questions/1665/configure-external-interface-for-dhcpv6-client-on-cisco-ios
I am getting a 2601:8:a881:9600/64 on the Router wan port and a 2601:8:a881:96FF/64 on the Router LAN port but in the External Router Delegated Prefix section it's blank. My clients receive 2601:8:a881:96ff/64 addresses and it can ping the Router IP addresses but cant ping the modem IPs. The router pings ipv6 sites just fine. My firmware is 22.214.171.124. What gives???
