今天开始学习FRR，完成如下几个目标：

1. 配置，编译，安装FRR
2. 启动

解决依赖问题

sudo apt-get install autoconf
sudo apt-get install libtool   
sudo apt-get install libsysfs-dev
sudo apt-cache search libjson-c-dev
sudo apt-get install libjson-c-dev
sudo apt-get install libpython-dev
sudo apt-get install python-pkgconfig
sudo apt-get install libreadline-dev
sudo apt-get install libc-ares-dev
sudo apt-cache search libyang
sudo apt-get install libyang-dev
sudo apt-get install libbison-dev

配置

#在frr源码目录下

./bootstrap.sh 
./configure

添加用户和组

sudo groupadd frr 
sudo useradd frr
sudo useradd frr -g frr
chown frr:frr /var/run/
sudo 777 /var/run/
sudo chmod 777 /var/run/
sudo chmod 777 /usr/local/etc/
chown frr:frr /usr/local/etc/

编译安装

#解决依赖命令
sudo apt-get install libfl-dev

#make
make

#install
make install

启动

cp /usr/local/etc/bgpd.conf.sample /usr/local/etc/bgpd.conf
cp /usr/local/etc/zebra.conf.sample /usr/local/etc/zebra.conf
cp /usr/local/etc/vtysh.conf.sample /usr/local/etc/vtysh.conf
sudo cp /usr/local/lib/libfrr.so.0 /lib/
sudo zebra -d
sudo bgpd -d
ubuntu@ubuntu:~$ sudo vtysh
