0x01 安装依赖 $ sudo apt update$ sudo 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 $ sudo apt install cmake libpcre3-dev$ git clone https://github.com/CESNET/libyang.git$ cd libyang$ mkdir build$ cd build$ cmake -DENABLE_LYD_PRIV=ON -DCMAKE_INSTALL_PREFIX:PATH=/usr -D CMAKE_BUILD_TYPE:String="Release" ..$ make$ sudo make install $ sudo apt-get install protobuf-c-compiler libprotobuf-c-dev$ sudo apt-get install libzmq5 libzmq3-dev 0x02 安装frr 1、添加frr用户和组 $ sudo groupadd -r -g 92 frr$ sudo groupadd -r -g 85 frrvty$ sudo adduser --system --ingroup frr --home /var/run/frr/ --gecos "FRR suite" --shell /sbin/nologin frr$ sudo usermod -a -G frrvty frr 2、编译 $ git clone https://github.com/frrouting/frr.git frr$ cd frr$ ./bootstrap.sh$ ./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 --with-pkg-extra-version=-MyOwnFRRVersion --enable-systemd=yes --enable-doc-html --enable-rpki --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$ sudo make install（保持当前所在目录不变更）
3、安装frr配置文件 $ sudo install -m 775 -o frr -g frr -d /var/log/frr$ sudo install -m 775 -o frr -g frrvty -d /etc/frr$ sudo install -m 640 -o frr -g frrvty tools/etc/frr/vtysh.conf /etc/frr/vtysh.conf$ sudo install -m 640 -o frr -g frr tools/etc/frr/frr.conf /etc/frr/frr.conf$ sudo install -m 640 -o frr -g frr tools/etc/frr/daemons.conf /etc/frr/daemons.conf$ sudo install -m 640 -o frr -g frr tools/etc/frr/daemons /etc/frr/daemons 4、调整sysctlssldmy/etc/sysctl.conf：
net.ipv4.ip_forward=1net.ipv6.conf.all.forwarding=1运行sysctl -p更hxdbz/p> 5、添加MPLS内核模块
sldmy/etc/modules-load.d/modules.conf：
# Load MPLS Kernel Modulesmpls_routermpls_iptunnel保存后执行：
$ sudo modprobe mpls-router mpls-iptunnel 6、开启MPLS转发sldmy/etc/sysctl.conf：
# Enable MPLS Label processing on all interfacesnet.mpls.conf.eth0.input=1net.mpls.conf.eth1.input=1net.mpls.conf.eth2.input=1net.mpls.platform_labels=100000 7、安装服务文件 $ sudo install -m 644 tools/frr.service /etc/systemd/system/frr.service$ sudo systemctl enable frr 8、开启守护程序sldmy/etc/frr/daemons，比要开启的选项改为yes
9、添加服务端口sldmy/etc/services：
zebrasrv 2600/tcp # zebra servicezebra 2601/tcp # zebra vtyripd 2602/tcp # RIPd vtyripngd 2603/tcp # RIPngd vtyospfd 2604/tcp # OSPFd vtybgpd 2605/tcp # BGPd vtyospf6d 2606/tcp # OSPF6d vtyospfapi 2607/tcp # ospfapiisisd 2608/tcp # ISISd vtybabeld 2609/tcp # BABELd vtynhrpd 2610/tcp # nhrpd vtypimd 2611/tcp # PIMd vtyldpd 2612/tcp # LDPd vtyeigprd 2613/tcp # EIGRPd vtybfdd 2617/tcp # bfdd vtyfabricd 2618/tcp # fabricd vtyvrrpd 2619/tcp # vrrpd vty 10、启动frr $ systemctl enable frr$ systemctl start frr使用systemctl stop frr停止frr
使用systemctl restart frr杀死当前所有进程并重启frr
使用systemctl reload frr重新加载更新配置后的frr
