Netgear XCM8810 - 8800 SERIES 10-SLOT CHASSIS SWITCH ユーザーズマニュアル

A 6to4 tunnel connects one IPv6 region with multiple IPv6 regions. Only one 6to4 tunnel can 
be configured on a single router. 

To create an IPv6-to-IPv4 tunnel, use the following command:

create tunnel <tunnel_name> 6to4 source <source-address>

The 

source-address

 is an existing address in the switch. 

To delete a tunnel, use the following command:

delete tunnel <tunnel_name>

To configure or unconfigure IPv6 addresses for the tunnels, use the following commands:

configure tunnel <tunnel_name> ipaddress [ipv6-link-local | {eui64} 

<ipv6_address_mask> ]

unconfigure tunnel <tunnel_name> ipaddress <ipv6_address_mask>

To display tunnel information, use the following command:

show [{tunnel} {<tunnel_name>}]

Verifying the IP Unicast Routing Configuration

To display the currently configured routes, which includes how each route was learned, use 
the following command:

show iproute ipv6

Additional verification commands include:

show neighbor-discovery cache ipv6

—Displays the neighbor discovery cache of the 

system.

show ipconfig ipv6

—Displays configuration information for one or more VLANs.

show ipstats ipv6

—Displays the IPv6 statistics for the switch or for the specified VLANs. 

Configuring Route Sharing

IP route sharing allows multiple equal-cost routes to be used concurrently. IP route sharing 
can be used with static routes and OSPF routes. In OSPF, this capability is referred to as 
equal cost multipath (ECMP) routing.
