2002 : IPv4 address : Subnet ID : The IPv4 address above the interface ID is the public network IPv4 address obtained by A or B. Note that this public network IP is very important. This public network IP change may lead to IPv6. Intranet IPv6 had to be readdressed. And, of course, this IPv4 address cannot use a private IPv4 address. Ipv6 enable You can learn these two external routes. 1/32 Image The configuration of A and B is extremely simple, so I won’t say it here. Untagged An IPv6 unicast address corresponds to a Solicited-node address. The valid range of the Solicited-node address is the local link range. !

If there is a main class route in the routing table,ccna certification training, then the subnet is searched. If there is a subnet route, the query is limited to these subnets and further searched. If the final lookup fails (no subnet matches this route), the packet is dropped even if there is a default route; if there is no local For the main class route, see if there is a default route. If there is, then it will be forwarded by default route. If not, the packet will be discarded.
