3Com Switch 8800 Advanced Software V5 Configuration Guide

Configuring IPv6 Manually Configured Tunnel 381
n
For the configuration of tunnel interface MTU, refer to the ipv6 mtu command in
the Switch 8800 Command Reference Guide.

CAUTION:
■ After a tunnel interface is deleted, all the above features configured on the
tunnel interface will be deleted.
■ If the tunnel interface addresses 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 can configure static or dynamic routes. IP addresses must be
configured at both ends of the tunnel. For detailed configuration, refer to
“IP
Routing and Routing Table” on page 187.
Configure an
IPv6 address
for the tunnel
interface
Configure a global
unicast IPv6 address
or a site-local
address
ipv6 address {
ipv6-address prefix-length
|
ipv6-address/prefix-length
}
Required
Use any command.
By default, no IPv6 global
unicast address or
site-local address is
configured for the tunnel
interface.
ipv6 address
ipv6-address/prefix-length
eui-64
Configure a
link-local IPv6
address
ipv6 address auto
link-local
Optional
A link-local address will
automatically be created
when an IPv6 global
unicast address or
site-local address is
configured.

Required
By default, the tunnel is a
GRE tunnel. The same
tunnel type should be
configured at both ends of
the tunnel. Otherwise,
packet delivery will fail.
Configure a source address or source
interface for the tunnel
source { ip-address |
ipv6-address |
interface-type
interface-number }
Required
By default, no source
address or interface is
configured for the tunnel.
Configure a destination address for
the tunnel
destination ip-address Required
By default, no destination
address is configured for
the tunnel.

ID to be referenced by the tunnel
interface
