**第-1步，安装samba（我是先下载**V7.1到了本地，其实可以直接git clone下载即可，安装samba是为了copy进去**）**

下载releases发布的版本 V7.1到了本地  
https://github.com/FRRouting/frr/releases

apt-get install samba samba-common

vim /etc/samba/smb.conf  
复制到文末：  
\[work code\]  
   comment = work  
   path = /home  
   public = yes  
   writeable  = yes  
   available = yes  
   browseable = yes  
   creat mask = 0777  
   directory mask = 0777  
   guest ok = yes

forceuser=root  
   forcegroup=root

执行 service smbd restart

**第0步、环境确认**  
XX:/code/frr\# uname -r  
4.15.0-54-generic  
XX:/code/frr\# cat /etc/issue  
Ubuntu 18.04.3 LTS \\n \\l

**第一步、安装依赖关系**  
apt update  
apt-get update  
apt-get install \\  
   git autoconf automake libtool make libreadline-dev texinfo \\  
   pkg-config libpam0g-dev libjson-c-dev bison flex python3-pytest \\  
   libc-ares-dev python3-dev libsystemd-dev python-ipaddress python3-sphinx \\  
   install-info build-essential libsystemd-dev libsnmp-dev perl libcap-dev  
autoreconf -ivf

**第二步、安装FRR依赖于的libyang库 **  
wget https://ci1.netdef.org/browse/LIBYANG-YANGRELEASE-10/artifact/shared/Debian-AMD64-Packages/libyang0.16\_0.16.105-1\_amd64.deb   
wget https://ci1.netdef.org/browse/LIBYANG-YANGRELEASE-10/artifact/shared/Debian-AMD64-Packages/libyang-dev\_0.16.105-1\_amd64.deb   
dpkg -i libyang0.16\_0.16.105-1\_amd64.deb  
apt-cache policy libpcre32-3  
apt-cache policy libpcrecpp0v5  
apt-get install libpcre16-3=2:8.39-9 libpcre32-3=2:8.39-9 libpcrecpp0v5=2:8.39-9 libpcre3-dev  
dpkg -i libyang-dev\_0.16.105-1\_amd64.deb  
apt-get install protobuf-c-compiler libprotobuf-c-dev  
apt-get install libzmq5 libzmq3-dev

**第三步、添加FRR用户和组**  
groupadd -r -g 92 frr  
groupadd -r -g 85 frrvty  
adduser --system --ingroup frr --home /var/run/frr/ \\  
   --gecos "FRR suite" --shell /sbin/nologin frr  
usermod -a -G frrvty frr

**第四步、编译**  
./configure \\  
    --prefix=/usr \\  
    --includedir=\\$\{prefix\}/include \\  
    --enable-exampledir=\\$\{prefix\}/share/doc/frr/examples \\  
    --bindir=\\$\{prefix\}/bin \\  
    --sbindir=\\$\{prefix\}/lib/frr \\  
    --libdir=\\$\{prefix\}/lib/frr \\  
    --libexecdir=\\$\{prefix\}/lib/frr \\  
    --localstatedir=/var/run/frr \\  
    --sysconfdir=/etc/frr \\  
    --with-moduledir=\\$\{prefix\}/lib/frr/modules \\  
    --with-libyang-pluginsdir=\\$\{prefix\}/lib/frr/libyang\_plugins \\  
    --enable-configfile-mask=0640 \\  
    --enable-logfile-mask=0640 \\  
    --enable-snmp=agentx \\  
    --enable-multipath=64 \\  
    --enable-user=frr \\  
    --enable-group=frr \\  
    --enable-vty-group=frrvty \\  
    --with-pkg-git-version \\  
    --enable-systemd=yes \\  
    --enable-doc-html --enable-ripd --enable-ripngd --enable-ldpd --enable-bgpdd --enable-eigrpd --enable-gcc-rdynamic --enable-watchfrr --enable-datacenter --enable-vtysh --enable-backtrace --enable-ospfapi --enable-ospfclient --enable-isisd --enable-snmp --enable-multipath=6 --enable-shell-access --disable-sysrepo --enable-fpm  
    make && make install

**第五步、安装FRR配置文件**  
install -m 775 -o frr -g frr -d /var/log/frr  
install -m 775 -o frr -g frrvty -d /etc/frr  
install -m 640 -o frr -g frrvty tools/etc/frr/vtysh.conf /etc/frr/vtysh.conf  
install -m 640 -o frr -g frr tools/etc/frr/frr.conf /etc/frr/frr.conf  
install -m 640 -o frr -g frr tools/etc/frr/daemons.conf /etc/frr/daemons.conf  
install -m 640 -o frr -g frr tools/etc/frr/daemons /etc/frr/daemons

**第六步、调整的sysctl **  
1、vim /etc/sysctl.conf  
\# Uncomment the next line to enable packet forwarding for IPv4  
net.ipv4.ip\_forward=1

\# Uncomment the next line to enable packet forwarding for IPv6  
\#  Enabling this option disables Stateless Address Autoconfiguration  
\#  based on Router Advertisements for this host  
net.ipv6.conf.all.forwarding=1

2、vim /etc/modules-load.d/modules.conf  
\# Load MPLS Kernel Modules  
mpls\_router  
mpls\_iptunnel

执行modprobe mpls-router mpls-iptunnel

启用MPLS转发  
编辑/etc/sysctl.conf和以下行。确保为net.mpls.conf.eth0.inputMPLS使用的每个接口添加等于的行。

\# Enable MPLS Label processing on all interfaces  
net.mpls.conf.eth0.input=1  
net.mpls.conf.eth1.input=1  
net.mpls.conf.eth2.input=1  
net.mpls.platform\_labels=100000

在执行sysctl -p

**第七步、启用守护进程**  
vim /etc/frr/daemons查找带有watchfrr\_enable=...和的部分zebra=...。通过将值更改为yes，根据需要启用守护进程。

**第八步、安装服务文件**  
install -m 644 tools/frr.service /etc/systemd/system/frr.service  
systemctl enable frr  
systemctl start frr

停止使用  
systemctl stop frr
