Configuration Example

C
ONFIGURATION
If the addresses of the tunnel interfaces at the two ends of a tunnel are not in
■
the same subnet, a forwarding route through the tunnel to the peer must be
configured so that the encapsulated packet can be forwarded normally. You
can configure static or dynamic routes. IP addresses must be configured at
both ends of the tunnel. For detailed configuration, refer to
and Dynamic Routing" on page
When you configure a static route, you need to configure a route to the
■
destination address (the destination IPv6 address of the packet, instead of the
IPv4 address of the tunnel destination) and set the next-hop to the tunnel
interface number or network address at the local end of the tunnel. Such
configurations must be performed at both ends of the tunnel.
The destination address of a tunnel packet must not be within the subnet of
■
the tunnel interfaces.
Before configuring dynamic routes, you must enable the dynamic routing
■
protocol on the tunnel interfaces at both ends. For related configurations, refer
to "Static Routing and Dynamic Routing" on page
The destination address of the route configured on the tunnel interface and
■
the address of the tunnel interface must not be in the same subnet.
Network requirements
Two IPv6 networks are connected through an IPv6 manually configured tunnel
between Router A and Router B. As shown in
A can communicate with Ethernet 1/0 on Router B normally and an IPv4 packet
route is available between.

Configuration procedure
The following example shows how to configure an IPv6 manually configured
tunnel between Router A and Router B. Before configuration, you must specify IP
addresses for the source and destination of the tunnel.
