Enabling DHCPv6 Rapid Commit Support
You can configure the DHCPv6 local server to support the DHCPv6 Rapid Commit option
(DHCPv6 option 14). When rapid commit is enabled, the server recognizes the Rapid
Commit option in Solicit messages sent from the DHCPv6 client. (DHCPv6 clients are
configured separately to include the DHCPv6 Rapid Commit option in the Solicit
messages.) The server and client then use a two-message exchange (Solicit and Reply)
to configure clients, rather than the default four-message 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.
You can configure the DHCPv6 local server to support the Rapid Commit option globally,
for a specific group, or for a specific interface. By default, rapid commit support is disabled
on the DHCPv6 local server.
To configure the DHCPv6 local server to support the DHCPv6 Rapid Commit option:
1. Specify that you want to configure the overrides options:
[edit system services dhcp-local-server dhcpv6]
user@host# edit overrides
2. Enable rapid commit support:
[edit system services dhcp-local-server dhcpv6 overrides]
user@host# set rapid-commit
