Configuring IPv6 Manual Tunnel 527
c
CAUTION:
■ 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. 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
“Routing Policy Configuration” on page 415 or “Routing Policy Configuration”
on page 489.
■ 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.
■ Before configuring dynamic routes, you must enable the dynamic routing
protocol on the tunnel interfaces at both ends. For related configurations, refer
to “Routing Policy Configuration” on page 489.
■ 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.
Configuration Example Network requirements
Two IPv6 networks are connected through an IPv6 manual tunnel between Switch
A and Switch B. As shown in Figure 159, VLAN-interface 100 on Switch A can
communicate with VLAN-interface 100 on Switch B normally via an IPv4 route.
Configure a source address or
interface for the tunnel
source { ip-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.
Reference an aggregation group aggregation-group
aggregation-group-id
Required
By default, no link
aggregation group ID is
referenced.
