Introduction to IPv6 routers

Through understanding IPv6 and in-depth research, we find that the IPv6 router address is closely related to the host, which is also a unique place for IPv6 addresses. Now let's learn about IPv6 host addresses and IPv6 router addresses based on what we have learned before.

How many addresses does an IPv6 host have?

Generally, an IPv6 host has multiple IPv6 addresses, even if the host has only one single interface. An IPv6 host can have the following spof addresses at the same time:

◆ Local link address of each interface;

◆ The unicast address of each interface can be a local site address and one or more global addresses that can be aggregated );

◆ Loopback) the loopback address of the interface: 1 ).

In addition, each host must always listen to the information on the following multi-point transfer address:

◆ All multicast addresses of nodes within the local range of the node FF01: 1 );

◆ All node multicast addresses in the local range of The Link FF02: 1 );

◆ Request node solicited-node) multicast address if an interface of the host is added to the request node group );

◆ Multicast address if an interface of the host is added to any multicast group ).

How many addresses does an IPv6 router have?

An IPv6 router can be assigned the following spof addresses:

◆ Local link address of each interface;

◆ The unicast address of each interface can be a local site address and one or more global addresses that can be aggregated );

◆ Subnet-vro any playback address;

◆ Other playback addresses are optional );

◆ Loopback address of the loopback interface: 1 ).

In addition to the preceding addresses, the router must always listen to the information flow from the following multicast addresses:

◆ All node multicast addresses within the local range of the node FF01: 1 );

◆ All vro multicast addresses within the local range of the node FF01: 2 );

◆ All node multicast addresses within the local range of The Link FF02: 1 );

◆ All vro multicast addresses within the local range of The Link FF02: 2 );

◆ All vro multicast addresses in the local area of the site FF05: 2 );

◆ Request node solicited-node) multicast address if an interface of the router is added to the request node group );

◆ Multicast address if an interface of the router is added to any multicast group ).
