About this chapter
What this chapter covers
This chapter moves from theory to the first real configuration on a RouterOS device.
It shows how addresses are added to interfaces, how neighbours and routers find each other on a link, and how the router decides where to send a packet. These three ideas are the core of a working IPv6 network.
You will see the console commands for each one, and the flags and columns you need to read in the output.
How the topics fit together
An address makes an interface reachable, Neighbor Discovery makes the link work, and routing connects links.
The first page covers the address configuration. A router can hold a link local address and several global addresses on one interface. You add them by hand, with EUI-64, from a pool, or by accepting them from a neighbour.
The advertise setting decides whether the prefix is passed to hosts.
The second page covers Neighbor Discovery. It explains how a host finds the MAC address of a neighbour, how routers announce prefixes, and what the M and O flags tell a host to do. It also shows the /ipv6 nd settings and the neighbour cache.
The third page covers routing basics and prefixes. It explains connected and static routes, the longest prefix match, the default route ::/0, and why a link local gateway needs an interface name.
Many faults in a new IPv6 setup come from one of these three layers. Check the address first, then the neighbour cache, then the route table.
How to use these pages
Each topic page has the same shape, so you can skim for what you need.
- What it is: the idea in plain words.
- How it works: the mechanism, with diagrams and example commands.
- What to remember for the exam: the facts to memorise.
- Common mistakes: the classic traps.
- Check yourself: three questions to test your understanding.
These pages work best with a router or a lab image in front of you. Add an address, look at /ipv6 address print, then check /ipv6 neighbor print and /ipv6 route print and see what appeared. Matching each output line to the idea behind it is the fastest way to learn.
Later chapters build on this one. The security chapter returns to Neighbor Discovery messages, and the interoperability chapter returns to pools and routing protocols.
