rapid-commit DGS-3130 Layer 3 Stackable Managed Switch CLI Reference Guide (Optional) Specifies to use a two-message exchange instead of the standard four-message exchange between the Requesting Router (RR) and the Delegating Router (DR) to obtain the network configuration settings from the DHCP Server. By default, two-message exchange is not allowed. Default None. Command Mode Interface Configuration Mode. Command Default Level Level: 12. Usage Guideline This command enables DHCP for IPv6 server service on a specified interface. An IPv6 DHCP pool can be associated with multiple interfaces. The pool must be configured before it can be associated. Only one IPv6 DHCP pool can be associated with an interface. The DHCP for the IPv6 client, server, and relay functions are mutually exclusive on an interface. The standard four-message exchange between the DR and the RR includes four messages: SOLICIT, ADVERTISE, REQUEST, and REPLY. When the rapid-commit parameter is specified, the RR will notify the DR in the SOLICIT message that it can skip receiving the ADVERTISE message and sending REQUEST message, and proceed directly with receiving the REPLY message from DR to complete a two-message exchange instead of the standard four-message exchange. The REPLY message contains the network configuration settings. The rapid-commit parameter must be enabled on both the DR and the RR to function properly. Example This example shows how to create the DHCP pool "pool1", enable the DHCP IPv6 server service on the interface VLAN 100 using the DHCP pool "pool1" to delegate the prefixes. Switch# configure terminal Switch(config)# ipv6 dhcp pool pool1 Switch(config-dhcp)# exit Switch(config)# interface vlan 100 Switch(config-if)# ipv6 dhcp server pool1 Switch(config-if)# 25-9 ipv6 local pool This command is used to configure a local IPv6 prefix pool. Use the no form of this command to remove the pool. ipv6 local pool POOL-NAME IPV6-PREFIX/PREFIX-LENGTH ASSIGNED-LENGTH no ipv6 local pool POOL-NAME Parameters POOL-NAME IPV6-PREFIX PREFIX-LENGTH Specifies the name of the local IPv6 prefix pool with a maximum of 12 characters. Specifies the IPv6 prefix address of the local pool. Specifies the IPv6 prefix length of the local pool. 282
