Troubleshooting BGP for IPv6

BGP for IPv4 and BGP for IPv6 are configured in the same BGP autonomous system configuration mode. This is known as Multiprotocol BGP, or MP-BGP for short. Implementing BGP for IPv4 and IPv6 on the same router requires the use of address families and the activation of neighbors for those address families. This section examines the additional issues (on top of what was already covered thus far in the chapter) that you may encounter when using MP-BGP with IPv4 and IPv6 unicast routes. Refer to Figure 18-8 while reviewing this section.

Figure shows the basic topology of MP-BGP protocols.
