Configuring the 6in4 Internet Transition Mechanism
Use these commands to move IPv6 traffic over a network that does not support IPv6. The commands use the 6in4 Internet transition protocol to encapsulate IPv6 traffic for IPv4 links.
To create 6in4 virtual interfaces:
Run these commands in this order:
> add interface <physical-if> 6in4 <6in4-id> remote <remote_ipv4_ip> [ttl <ttl>]
> set interface <sit_if_name> ipv6-address <ipv6_address> mask-length 64
Adding the Interface
Use this command to add the interface.
Syntax
> add interface <physical_if> 6in4 <6in4_id> remote <remote_ipv4> [ttl <ttl>]
Parameter
|
Description
|
<physical_if>
|
The physical interface encapsulated traffic leaves the system from.
For example:
eth1-01
|
<6in4_id>
|
A numerical identifier for the 6in4 Virtual Interface.
|
<remote_ipv4_ip>
|
IPv4 address of the remote peer.
|
<ttl>
|
Time-to-live: the number of router hops before packets are discarded.
|
Example
> add interface eth1-01 6in4 999 remote 50.50.50.10
1_01:
Success
Notes
Use this command to set the interface.
Syntax
> set interface <sit_if_name> ipv6-address <ipv6_address> mask-length 64
Parameter
|
Description
|
<sit_if_name>
|
The name of the virtual interface, which begins: sit_6in4_<ID_num_from_previous_command>
|
<ipv6_address>
|
IPv6 address
|
Example
> set interface sit_6in4_999 ipv6-address 30:30:30::1 mask-length 64
Output
1_01:
Success
To delete the 6in4 Virtual Interface:
Run:
> delete interface <physical_if> 6in4 <6in4_id>
Example
> delete interface eth1-01 6in4 999
Output
1_01:
success
asg search and 6in4
- When you use
asg search to discover which SGM handles a specific connection (actively or as backup) and which Chassis, IPv4 addresses of a remote peer can show as being handled by more than 1 SGM. asg search on IPv6 addresses shows:- 1 SGM on the active Chassis
- 1 SGM on the standby Chassis
