z
If the addresses of the tunnel interfaces at the two ends of a tunnel are not in the same network
segment, a route to the peer must be configured at both ends so that the encapsulated packet can
be forwarded normally. You can configure static or dynamic routing. Automatic tunnels do not
support dynamic routing. For the detailed configuration, refer to Static Routing Configuration or
other routing protocol configuration in the IP Routing Volume .
z
The automatic tunnel interfaces using the same encapsulation protocol cannot share the same
source IP address.
z
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.
Configuration Example
Network requirements
As shown in Figure 1-10 , an IPv6 network is connected to an IPv4 network through an ISATAP switch.
The destination address of the tunnel is an ISATAP address. It is required that IPv6 hosts in the IPv4
network can access the IPv6 network through the ISATAP tunnel.

Configuration procedure
z
Make sure that the corresponding VLAN interfaces have been created on the switch.
z
Make sure that VLAN-interface 101 on the ISATAP switch and the ISATAP host are reachable to
each other.
