Configuring the DHCPv6 Client Rapid Commit Option
The DHCPv6 client can obtain configuration parameters from a DHCPv6 server through a rapid two-message exchange (solicit and reply). When the rapid commit option is enabled by both the DHCPv6 client and the DHCPv6 server, the two-message exchange is used, rather than the default four-method exchange (solicit, advertise, request, and reply). The two-message exchange provides faster client configuration and is beneficial in environments in which networks are under a heavy load.
To configure the DHCPv6 client to support the DHCPv6 rapid commit option:
- Specify the DHCPv6 client interface.[edit]user@host# set interfaces ge-0/0/0 unit 0 family inet6 dhcpv6-client
- Configure the two-message exchange option for address
assignment.[edit interfaces ge-0/0/0 unit 0 family inet6 dhcpv6-client]user@host# set rapid-commit
