What are the necessary steps to configure IOS 12.4(25f) to support IPv6? Comcast is the ISP, and I'll be using a Server 2012 box for internal DHCPv6.
I'll need to grab a DHCPv6 address from Comcast for the external interface.
So far, on my external interface, I have:
ipv6 address autoconfig default ipv6 enable ipv6 traffic-filter al in ipv6 verify unicast reverse-path ipv6 dhcp client pd comcast-ipv6
For the 'al' access-list, I have:
permit udp any any eq 546
