Creating a static mapping

Situations exist in which it makes sense to map a specific IPv6 address to a specific host rather than dynamically assign an IP address from a pool of addresses. This mapping is known as a static mapping.

A static mapping is defined by using the static-mapping option of the service dhcp-server configuration node.

The following example shows how to map the 2001:db8:100::101 IP address to the device with a MAC address of 00:0c:29:34:91:45.

Table 1. Creating a static mapping

Step

Command

Create a static mapping called lab and specify the static IP address.


vyatta@R1#set service dhcpv6-server static-mapping lab ipv6-address 2001:db8:100::101

Specify the host identifier string ( "00:0c:29:34:91:45"- 6 bytes of host MAC address) within the static mapping called lab.


vyatta@R1#set service dhcpv6-server static-mapping lab identifier 00:0c:29:34:91:45

Commit the information.


vyatta@R1# commit

Show the configuration.


vyatta@R1# show service dhcp-server shared-network-name LAB-NET
       static-mapping lab
   {
       ipv6-address 2001:db8:100::101
       identifier 00:0c:29:34:91:45
   }
