Tunneling Configuration Task List; Configuring Ipv6 Manual Tunnel - H3C S7500E Series Operation Manual

destination address of an IPv6 packet and the IPv6 address of a tunnel interface both
adopt special addresses: ISATAP addresses. The ISATAP address format is
prefix(64bit):0:5EFE:ip-address. The ip-address is in the form of a.b.c.d or abcd:efgh,
where abcd:efgh represents a 32-bit source IPv4 address. Through the embedded IPv4
address, an ISATAP tunnel can automatically be created to transfer IPv6 packets. The
ISATAP tunnel is mainly used for connection between IPv6 routers or between a host
and an IPv6 router over an IPv4 network.

3.3 Configuring IPv6 Manual Tunnel

3.3.1 Configuration Prerequisites
IP addresses are configured for interfaces such as the VLAN interface and loopback
interface on the device. These interfaces serve as the source interfaces of tunnel
interfaces to ensure that the tunnel destination addresses are reachable.
