Caution:
z
After a tunnel interface is deleted, all the above features configured on the tunnel
interface will be deleted.
z
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. The route
can be a static or dynamic route. IP addresses must be configured at both ends of
the tunnel. For detailed configuration, refer to
IPv4 Routing Configuration or IPv6
Routing Configuration
.
z
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.
z
Before configuring dynamic routes, you must enable the dynamic routing protocol
on the tunnel interfaces at both ends. For related configurations, refer to
IPv6
Routing Configuration
.
z
The destination address of the route configured on the tunnel interface and the
address of the tunnel interface must not be in the same network segment.
z
Before referencing a link aggregation group on the tunnel interface to receive and
send packets, make sure that the aggregation group has been configured.
Otherwise, the tunnel interface will not be up to communicate.
3.3.3 Configuration Example
I. Network requirements
Two IPv6 networks are connected through an IPv6 manual tunnel between Switch A
and Switch B. As shown in
, VLAN-interface 100 on Switch A can
communicate with VLAN-interface 100 on Switch B normally via an IPv4 route.
