In this episode, Ed, Scott, and Tom get technical with a discussion of IPv6 Router Advertisements (RAs), what they are, what they’re for, what information they contain, new and future RA options, and what you need to know about them to help deploy IPv6 effectively.
Topics discussed include:
- What is an IPv6 RA and where does it fit within the overall process of IPv6 Neighbor Discovery (ND)
- Some well-known options for a “normal RA” – what does it look like – SLAAC/DHCPv6
- Mature, new, and proposed RA options (RDNSS, PREF64, the S flag) and what they do
Thanks for listening!
