33.33.33.16/28
33.33.33.32/32
The NAT rule does map the traffic coming from 20.20.0.0/16 to public address range 33.33.33.1 to 33.33.33.32.

8 Configuration Tips

Currently, there is no support for fragmentation and reassembly. Therefore, the administrator needs to properly
configure the MTUs on the IPv6 and IPv4 network.

9 Operations and Management

There are two classes of commands that can be used to check the workings of the 6rd implementation: CLI and
debug. The debug commands are used from the services DPC/PIC console, and the CLI follows the traditional
Juniper implementation.

9.1 6rd CLI

The administrator has several commands available to perform operations and management. The following sections
discuss a few of them. The user is referred to the appropriate Junos OS manual for a more complete set.

9.1.1 Flows and Conversations

The administrator can use the command "show services stateful-firewall flows" to check the creation of the softwires
and flows. An example output for the configuration previously discussed is shown in the following.
user@router# run show services stateful-firewall flows
Interface: sp-3/0/0, Service set: v6rd-dom1-dom3-service-set

Another important command shows the conversations (collection of related flows).
user@router# run show services stateful-firewall conversations
Interface: sp-3/0/0, Service set: v6rd-dom1-dom3-service-set
Conversation: ALG protocol: tcp
Number of initiators: 1, Number of responders: 1
