Configuration Example

CAUTION:
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. For the detailed configuration, refer to
"Static Routing and Dynamic Routing" on page
interfaces using the same encapsulation protocol must have different source
and destination addresses.
If the tunnel interface is the source interface, the source address is the primary
■
IP address of the source interface.
Before configuring dynamic routes, you must enable the dynamic routing
■
protocol on the tunnel interfaces at both ends of the tunnel. Such a route must
be configured at both ends of the tunnel. For related configurations, refer to
"Static Routing and Dynamic Routing" on page
Only the IPv6 over IPv6 tunnel has a maximum number of nested
■
encapsulations of a packet.
Network requirements
The two subnets Group 1 and Group 2 running IPv6 are interconnected by using
an IPv6 over IPv6 tunnel between Router A and Router B.
