Configuration Example - HP 4800G Series Configuration Manual

To do...
Configure a source address or
interface for the tunnel
Configure a destination
address for the tunnel
Reference a service loopback
group
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.
To reference a service loopback group ID on the tunnel interface to receive and send packets, you
must have configured the service loopback group. Otherwise, the tunnel interface will not be up to
communicate. For creation and configuration of a service loopback group, refer to Service
Loopback Group Configuration in the Access 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.
Use the command...
source { ip-address |
interface-type
interface-number }
destination ip-address
service-loopback-group
number
1-3, two IPv6 networks are connected to an IPv4 network through Switch A and
Required
By default, no source address
or interface is configured for the
tunnel.
Required
By default, no destination
address is configured for the
tunnel.
Required
By default, the tunnel does not
reference any service loopback
group.
