Single IPv4 BGP Session Versus Dual (IPv4 and IPv6) Sessions
At this point in this chapter, you have seen two approaches to support both the routing of IPv4 and IPv6 networks in a BGP environment. One option was to have a single IPv4 BGP session, and use that single session to carry IPv4 and IPv6 route information. The second option was to have an IPv4 BGP session, carrying just IPv4 network advertisements, and an IPv6 BGP session, carrying just IPv6 network advertisements.
While you can choose either approach to support IPv4 and IPv6 routing, from a design perspective, you should understand the benefits (and any drawbacks) of each approach. The following lists highlight the characteristics of each approach:
Single IPv4 BGP session:
