Configuration Example; Configuration Procedure - 3Com S7906E Configuration Manual

After a tunnel interface is deleted, all the above features configured on the tunnel interface will be
deleted.
If the addresses of the tunnel interfaces at the two ends of a tunnel are not in the same network
segment, a forwarding route through the tunnel to the peer must be configured so that the
encapsulated packet can be forwarded normally. You need to configure static or dynamic routing at
both ends of the tunnel. For detailed configuration, refer to Static Routing Configuration or other
routing protocol configuration in the IP Routing Volume.
When you configure a static route at one tunnel end, you need to configure a route to the
destination IPv6 address of the packet, instead of the IPv4 address of the tunnel destination, and
set the outbound interface to the tunnel interface at the local end or set the next-hop to the tunnel
interface at the peer end. The similar configuration needs to be performed at the other tunnel end.
When you configure dynamic routing at both tunnel ends, you need to enable the dynamic routing
protocol on the tunnel interfaces. For related configurations, refer to related contents in the IP
Routing Volume.

Configuration Example

Network requirements
As shown in Figure
Switch B respectively. Configure an IPv6 manual tunnel between Switch A and Switch B to make the
two IPv6 networks reachable to each other.

Configuration procedure

Make sure that Switch A and Switch B have the corresponding VLAN interfaces created and are
reachable to each other.
Configuration on Switch A
# Enable IPv6.
1-8, two IPv6 networks are connected to an IPv4 network through Switch A and
