Compile SRv6 uSID and VPP on ubuntu 20.04
11 7 月, 2020,由 frank撰写
PS: Compile Server base on “focal-server-cloudimg-amd64.vmdk”, 20200706 update.
General Config on ubuntu
Config port by new “ip” cmd, and DNS
root@server-test:/opt# ip addr add 10.75.37.59/24 dev ens4 # config addr for one port root@server-test:/opt# ip addr del 172.16.1.163/24 dev ens3 # delet addr for one port root@server-test:/opt# ip addr # equal with ifconfig root@server-test:/opt# ip link set ens4 up # up one port root@server-test:/opt# ip -s link ls ens4 # cool cmd, check RX/TX packets, errors, dropped, overrun, mcast root@server-test:/opt# ip route add default via 10.75.37.1 # config default route root@server-test:/opt# ip route # check v4 route table root@server-test:/opt# ip -6 route # check v6 route table root@server-test:/opt# echo 'nameserver 64.104.123.144' > /etc/resolv.conf
Permanent IP/DNS Config
Above cmd is temporary, after reboot, the config will disappear. If you want to permanent config IP/DNS, can config “netplan” that use YAML format:
root@server-test:/opt# more /etc/netplan/50-cloud-init.yaml
# This file is generated from information provided by the datasource. Changes
# to it will not persist across an instance reboot. To disable cloud-init's
# network configuration capabilities, write a file
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
# network: {config: disabled}
network:
ethernets:
ens3:
dhcp4: true
match:
macaddress: 5e:00:00:00:00:00
set-name: ens3
ens4:
dhcp4: no
addresses: [10.75.37.59/24]
gateway4: 10.75.37.1
nameservers:
addresses: [64.104.123.144]
match:
macaddress: fa:16:3e:47:6c:8a
set-name: ens4
version: 2
After config, update by follow cmd:
root@server-test:/opt# netplan apply
Update Source
root@server-test:/opt# cp /etc/apt/sources.list /etc/apt/sources.list.bak root@server-test:/opt# nano /etc/apt/sources.list root@server-test:/opt# more /etc/apt/sources.list #Ali Source deb http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse root@server-test:/opt# apt-get update

# This file provides an easy way to add custom menu entries. Simply type the
# menu entries you want to add after this comment. Be careful not to change
root@server1:/opt/trex/v2.81#
Boot id as follow summary:
menuentry: 0
submenu: 1
menuentry: 0 ‘Ubuntu, with Linux 5.6.0+’
menuentry: 1 ‘Ubuntu, with Linux 5.6.0+ (recovery mode)’
menuentry: 2 ‘Ubuntu, with Linux 5.4.0-40-generic’
menuentry: 3 ‘Ubuntu, with Linux 5.4.0-40-generic (recovery mode)’
Now boot by 5.6.0, if want to boot by 5.4.0, change “/etc/default/grub”:
root@other-server# grep GRUB_DEFAULT /etc/default/grub GRUB_DEFAULT="1>2"
“1” is submenu: 1
“2” is menuentry: 2
Compile iproute2 to support SRv6 uSID
root@server-test:/opt# ip -V ip utility, iproute2-ss200127 root@server-test:/opt# root@server-test:/opt# git clone -b srv6-usid-public https://github.com/netgroup/srv6-usid-linux-iproute2.git root@server-test:/opt# cd srv6-usid-linux-iproute2/ root@server-test:/opt/srv6-usid-linux-iproute2# make root@server-test:/opt/srv6-usid-linux-iproute2# make install root@server-test:/opt/srv6-usid-linux-iproute2# ip -V ip utility, iproute2-ss200330
From iproute2’s “make help”, not have build rpm or deb option, but we can direct tar the folder that includes the compiled file. Then move the tar file to other ubuntu, then extract tar file and direct to “make install”, we do not require a compile environment.
Compile vpp 20.09 on ubuntu 20.04
Compile vpp
Compile guide please follow: Building VPP Commands
Get vpp pacakages
After compiled by “make pkg-deb”, will generate follow packages that can be direct installed at other ubuntu 20.04:
root@server-test:/opt/vpp# find /opt/ -name "*.deb" -print /opt/vpp/build-root/vpp-plugin-core_20.09-rc0~193-gea7e7087d_amd64.deb /opt/vpp/build-root/libvppinfra-dev_20.09-rc0~193-gea7e7087d_amd64.deb /opt/vpp/build-root/vpp-plugin-dpdk_20.09-rc0~193-gea7e7087d_amd64.deb /opt/vpp/build-root/python3-vpp-api_20.09-rc0~193-gea7e7087d_amd64.deb /opt/vpp/build-root/libvppinfra_20.09-rc0~193-gea7e7087d_amd64.deb /opt/vpp/build-root/vpp-dbg_20.09-rc0~193-gea7e7087d_amd64.deb /opt/vpp/build-root/vpp-dev_20.09-rc0~193-gea7e7087d_amd64.deb /opt/vpp/build-root/vpp-api-python_20.09-rc0~193-gea7e7087d_amd64.deb /opt/vpp/build-root/vpp_20.09-rc0~193-gea7e7087d_amd64.deb
Install at other 20.04 Server
root@other-server:/opt/vpp# apt install python3-cffi root@other-server:/opt/vpp# dpkg -i * # maybe you will have "Errors were encountered while processing" # find the miss pacakage, install, will report "run 'apt --fix-broken install' to correct" root@other-server:/opt/vpp# apt --fix-broken install # will fix dependence issue, then install again root@other-server:/opt/vpp# dpkg -i *
