Configuring an IPv4 over IPv6 Tunnel
Only EB cards and SD cards support the IPv4 over IPv6 Tunnel.
Configuration Prerequisites
z Configure IP addresses for interfaces (such as the VLAN interface, and loopback interface) on the
device to ensure normal communication.
z Specify one of the above interfaces as the source interface of the tunnel.
z Ensure reachability between the tunnel source and destination addresses.
Configuration Procedure
Follow these steps to configure an IPv4 over IPv6 tunnel:
To do… Use the command… Remarks
Enter system view system-view —
Enable IPv6 ipv6
Required
By default, the IPv6 packet forwarding
function is disabled.
Enter tunnel interface view interface tunnel number —
Configure an IPv4 address
for the tunnel interface
ip address ip-address { mask |
mask-length } [ sub ]
Required
By default, no IPv4 address is configured
for the tunnel interface.
Specify the IPv4 over IPv6
tunnel mode
tunnel-protocol ipv4-ipv6
Optional
By default, the tunnel is a GRE over IPv4
tunnel. The same tunnel mode should be
configured at both ends of the tunnel.
Otherwise, packet delivery will fail.
Configure the source address
or interface for the tunnel
interface
source { ipv6-address |
interface-type interface-number }
Required
By default, no source address or
interface is configured for the tunnel.
