16.1 DHCP server configuration
Integrated DHCP server of the router allows you to configure LAN device network settings. Router DHCP server
is able to send additional options to network devices, for example:
default-router – IP address of the router used as default gateway;
domain-name – domain name which will be used by client while solving host names via domain name
system (DNS);
dns-server – list of domain name server addresses for the current network that should be known by the
client. Server addresses are listed in descending order of their preference.
16.1.1 Configuration algorithm
Step Description Command Keys
1 Enable IPv4/IPv6 DHCP server. esr(config)# ip dhcp-server [vrf
<VRF>]
<VRF> – VRF instance name,
set by the string of up to 31
characters, within which the
NTP server will operate. Set by
the string of up to 31
characters.
esr(config)# ipv6 dhcp-server [vrf
<VRF>]
2 Set the DSCP code value for the use in
IP headers of DHCP server egress
packets (optionally).
esr(config)# ip dhcp-server dscp
<DSCP>
<DSCP> – DSCP code value,
takes values in the range of
[0..63].
Default value: 61.
