Configuring the 6in4 Internet Transition Mechanism
Use this command to move IPv6 traffic over a network that does not support IPv6. The command uses 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-address> [ttl "ttl"]set interface <sit if name> ipv6-address <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 will leave the system from, for example eth1-01.
|
6in4-id
|
A numerical identifier for the 6in4 Virtual Interface.
|
remote-ipv4-address
|
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
- Despite having specified a single physical interface (
eth1-01) on the command line, the virtual (sit_6in4_) interface is created for eth1-01 on all SGMs. - To see the virtual interfaces for each SGM, run:
show interface eth1-01 6in4s.
Use this command to set the interface.
Syntax
set interface <sit if name> ipv6-address <address> mask-length 64
Parameter
|
Description
|
sit if name
|
The name of the virtual interface, which begins: sit_6in4_<ID_number given in previous command>.
|
address
|
IPv6 address.
|
Example
> set interface sit_6in4_999 ipv6-address 30:30:30::1 mask-length 64
1_01:
Success
Setting the Interface
|
|
Example
> set interface sit_6in4_999 ipv6-address 30:30:30::1 mask-length 64
1_01:
Success
|
|
Deleting the 6in4 Virtual Interface
Run: delete interface <physical-if> 6in4 <6in4-id>. For example:
> delete interface eth1-01 6in4 999
1_01:
success
Asg Search and 6in4
- When using the
asg search command to discover which SGM handles a specific connection (actively or as backup) and which Chassis, IPv4 addresses of a remote peer may show as being handled by more than 1 SGM. asg search run on IPv6 addresses show:- 1 SGM on the active Chassis
- 1 SGM on the standby Chassis
