Usage Scenario
To configure the rebinding time of IP addresses in an address pool, run the rebinding-time command.
If the client does not receive any responses from the server before the rebinding timer expires, it considers the original DHCP server unavailable and starts to broadcast a DHCPREQUEST packet. Any DHCP server on the network can reply to this request with a DHCPACK or DHCPNAK packet.
If the client receives a DHCPACK packet, the IP address can be continuously used. If the client receives a DHCPNAK packet, a new IP address needs to be requested.
Prerequisites
An address pool has been created using the ip pool command in the system view.
Precautions
The rebinding time for an IP address must be less than the address pool lease configured using the lease command and greater than the renewal time of the IP address configured using the renewal-time command.
If rebinding-time has been configured and is reconfigured to 0, this parameter automatically restores to the default value. If rebinding-time has not been configured before, the default value is used.
