vpp系列8-dhcp client

前言

vpp並無dhcp server功能，只有dhcp client功能，具體命令見這裏

dhcp server安裝

dhcp server採用isc-dhcp-server，具體安裝見我另外一篇文章

注意，要確保二層是通的

vpp dhcp client配置

cli

set dhcp client [del] intfc <interface> [hostname <name>].

usage

create interface vmxnet3 0000:13:00.0 bind

#添加
set dhcp client intfc vmxnet3-0/13/0/0 hostname vppgate
#查看
show dhcp client intfc vmxnet3-0/13/0/0
#刪除
set dhcp client del intfc vmxnet3-0/13/0/0

測試

此時show dhcp client查看已經分配了10.241.100.11的IP

vpp# show int addr
local0 (dn):
vmxnet3-0/13/0/0 (up):
  L3 10.241.100.11/16
vpp# show dhcp client
[0] vmxnet3-0/13/0/0 state DHCP_BOUND installed 1 addr 10.241.100.11/16 gw 10.241.255.254 server 10.241.4.6 dns 8.8.8.8 dns 4.4.4.4

去dhcp server端查看分配狀況， cat /var/lib/dhcp/dhcpd.leases

lease 10.241.100.11 {
  starts 0 2020/08/16 15:39:26;
  ends 0 2020/08/16 15:49:26;
  cltt 0 2020/08/16 15:39:26;
