Outside the scope of this book, other router features can filter the topology data sent between routers. But for now, if the neighbor comes up, you can assume they exchange the topology data.

Thankfully, the EIGRPv6 topology data works just like it does for EIGRPv4, other than one obvious difference: It lists IPv6 prefixes. The following list points out the concepts that remain identical between the two:

The metric components (bandwidth, delay, reliability, ...
