Configuring Ipv6 Tunnel - Zte ZXR10 5900E Configuration Manual

ZXR10 5900E Series Configuration Guide (IPv6)
Encapsulation: If the egress interface of the sent IPv6 packet is a tunnel interface,
à
the host first determines the tunnel type. If the tunnel is a 6to4 tunnel, the host
implements IPv4 header encapsulation. During the encapsulation, the source
address is user-configured whereas the destination address is obtained from
the destination address of the packet. The encapsulated packet is then sent
according to the IPv4 packet sending process.
Decapsulation: If the protocol number in the IPv4 header of the received IPv4
à
packet is 41, the host proceeds to the 6to4 decapsulation process and searches
for the matched tunnel number according to the source address of the packet.
If the tunnel number is found, the host removes the IPv4 header added during
tunnel encapsulation and delivers the remaining IPv6 packet to the IPv6 packet
receiving process for further handling.

3.2 Configuring IPv6 Tunnel

Configuring 6in4 Tunnel
To configure a 6in4 tunnel, perform the following steps:

Function
Creates an IPv6 tunnel
interface. To delete the tunnel
interface, use the no format of
the command.
The parameter <tunnel_no>
indicates the tunnel number.
The number of tunnel interfaces
that can be created ranges
from 1 to 512.
Enters the IPv6 tunnel
configuration mode.
Enters the IPv6 tunnel interface
configuration mode.
Sets the current tunnel mode
tunnel
to 6in4. To cancel the current
tunnel mode, use the no format
of the command.
tunnel Specifies the source address
of the tunnel. To delete the
source address configuration
of the tunnel, use the no format
of the command.
