Step Description Command Keys
3 Create pool of DHCP server IPv4/IPv6
addresses and switch to its
configuration mode.
esr(config)# ip dhcp-server pool
<NAME> [vrf <VRF>]
<NAME> – IPv4/IPv6 server
profile name, set by the string
of up to 31 characters.
<VRF> – VRF instance name,
within which the NTP server
will operate. Set by the string of
up to 31 characters.
esr(config)# ipv6 dhcp-server pool
<NAME> [vrf <VRF>]
4 Specify IPv4/IPv6 address and mask
for the subnet from which IPv4/IPv6
addresses pool will be allocated.
esr(config-dhcp-server)# network
<ADDR/LEN>
<ADDR/LEN> – IP address and
prefix of a subnet, defined as
AAA.BBB.CCC.DDD/EE where
each part AAA-DDD takes
values of [0..255] and EE takes
values of [1..32].
esr(config-ipv6-dhcp-server)#
network <IPV6-ADDR/LEN>
<IPV6-ADDR/LEN> – IP
address and prefix of a subnet,
defined as X:X:X:X::X/EE where
each X part takes values in
hexadecimal format [0..FFFF]
and EE takes values of [1..128].
5 Add IPv4/IPv6 addresses range to the
address pool of configurable DHCP
server.
esr(config-dhcp-server)# address-
range <FROM-ADDR>-<TO-ADDR>
<FROM-ADDR> – range starting
IP address;
<TO-ADDR> – range ending IP
address;
The addresses are defined as
AAA.BBB.CCC.DDD where each
part takes values of [0..255].
You can specify up to 32 IP
addresses separated by
commas.
esr(config-ipv6-dhcp-server)#
address-range <FROM-ADDR>-
<TO-ADDR>
<FROM-ADDR> – range starting
IP address;
<TO-ADDR> – range ending IP
address;
The addresses are defined as
X:X:X:X::X where each part
takes values in hexadecimal
format [0..FFFF].
