The R6 configuration has only a single peer for IPv4 and IPv6, because it is a nonredundant
route reflector client. Under the IPv6 address family, a prefix is injected into BGP.
Summary
This chapter provided a high-level overview of IPv6 and using MP-BGP for IPv6 prefix
information. The subject of IPv6 is extensive, and many standards detail its operation. The
focus of this chapter was to help you understand how BGP has been modified to work with
IPv6 from an operational perspective.
The core of the BGP protocol remains the same with the MP-BGP extensions, allowing you
to leverage your BGP experience when you transition to IPv6. In many cases, the only
significant change is the format of the addressing. This chapter concluded with a case study
on deploying IPv6 alongside IPv4 in a dual-stack deployment, which is expected to be the
primary method of deploying IPv6.
