On the 24th of August 2016 Cisco released version 9.6.2 of its ASA software. The new version brings in more IPv6 support for the platform.
The ASA now supports the following features for IPv6 addressing:
- DHCPv6 Address client—The ASA obtains an IPv6 global address and optional default route from the DHCPv6 server.
- DHCPv6 Prefix Delegation client—The ASA obtains delegated prefix(es) from a DHCPv6 server. The ASA can then use these prefixes to configure other ASA interface addresess so that StateLess Address Auto Configuration (SLAAC) clients can autoconfigure IPv6 addresses on the same network.
- BGP router advertisement for delegated prefixes
- DHCPv6 stateless server—The ASA provides other information such as the domain name to SLAAC clients when they send Information Request (IR) packets to the ASA. The ASA only accepts IR packets, and does not assign addresses to the clients.
If you have loaded the new software how did you go in getting IPv6 working in your environment ?
At the moment I am trialing the new software on my carrier, to see whether I can get the full IPv4 and IPv6 dual stack working on the ASA platform.
