By default, the valid leasing period of IP address is 1 day.
6 Configure the IP Address of Egress Gateway Router for DHCP Clients
When a DHCP client accesses a server (or host) beyond the local subnetwork, all
the data must be sent and received via the egress gateway for the local network.
Only a maximum of 8 egress gateway addresses can be configured in each DHCP
address pool.
Perform the following configurations in DHCP address pool view.
Table 372 Configure the gateway router address of client
By default, the egress gateway address of DHCP client is not configured.
When specifying multiple egress gateway addresses, you need to continuously
configure up to two addresses in the gateway-list command, instead of using
this command repeatedly. That is because the new egress gateway address will
replace the previous one other than superimposing it.
7 Configure Domain Name of DHCP Client
In DHCP servers, the domain names used by the corresponding clients can be
specified respectively for each address pool.
Perform the following configurations in DHCP address pool view.
Table 373 Configure the domain names of DHCP clients
By default, the domain names allocated to DHCP clients are not configured.
8 Configure IP Address of DNS Used by DHCP Clients
When a computer accesses the Internet through the domain name, the domain
name should be resolved to IP addresses. To access the DHCP client to the Internet,
a DHCP server specifies the DNS address for the client when allocating the IP
address to it. Each DHCP address pool can be configured with up to a maximum of
8 DNS addresses.
Perform the following configurations in DHCP address pool view.
Table 374 Configure the DNS addresses in a DHCP address pool
By default, the IP address of DNS is not configured.
When specifying multiple DNS’s, you need to continuously configure up to two
addresses in the dns-list command, instead of using this command repeatedly.
