router clat

This command configures the device for the CLAT (customer-side translator) mechanism for 464XLAT.

464XLAT provides a simple technique for an IPv4 client with a private address to connect to an IPv4 host over an IPv6 network. 464XLAT only supports IPv4 in the client-server model, where the server has a global IPv4 address. This means, it's not suited for IPv4 peer-to-peer communication or inbound IPv4 connections.

The architecture includes the following components:

■

PLAT (provider-side translator): Translates N:1 global IPv6 addresses to global IPv4 addresses, and vice versa.

■

CLAT: Translates private IPv4 addresses to global IPv6 addresses, and vice versa. Only this component is supported by the device.

Syntax

router clat {ipv4-dst-network|ipv6-dst-prefix|ipv6-src-prefix}

Command	Description
ipv4-dst-network	Defines the IPv4 destination network to reach via translation (using CLAT).
ipv6-dst-prefix	Defines the IPv6 destination prefix (PLAT prefix).
ipv6-src-prefix	Defines the IPv6 source prefix (CLAT prefix).

Note

■

The IPv6 route must be entered in the destination prefix.

■

Up to 5 destination networks can be added.

■

The IPv6 source prefix can be added statically or by using prefix delegation interface

■

This command is applicable only to Mediant 500Li and Mediant 800Ci.
