So I've been trolling the Cisco forms and haven't round a suitable answer. While I was reading the new Cisco press books I found a lot a talk about these anycast addresses.
So my question is what address is an anycast address? I know you can make any address into one by using the anycast parameter after IP address command.
So I'll take an example from the press book. The author seems to use every subnet except for the 0000 subnet, the fourth quartet. Is that the subnet anycast address? (p.699)
To make it more confusing, It exists in every subnet. Which address is that? (p.723) It is when the interface ID are all zeros?
So 2001:0db8:1111:AAAA:0000:0000:0000:0000 is the anycast address for the subnet AAAA? Give it to me straight man! XD
You may have a look here for that "all routers anycast address". It is the ipv6 address with all hosts bits set to zero. All traffic sent to this address should be delivered to one router in that network, all routers in the network should implement that anycast address. Here is a discussion in CLN about that address: Using IPv6 Router Anycast Address
