IPv6 basics configuration example
Network requirements
As shown in
Ethernet ports into corresponding VLANs, configure IPv6 addresses for the VLAN interfaces and verify
that they are connected.
The global unicast addresses of VLAN-interface 1 and VLAN-interface 2 on Switch A are
•
2001::1/64 and 3001::1/64, respectively.
•
The global unicast address of VLAN-interface 2 on Switch B is 3001::2/64, and a route to Host is
available.
IPv6 is enabled for the host to automatically obtain an IPv6 address through IPv6 ND, and a route
•
to Switch B is available.
