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

调整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、
sysctl -p

启用守护线程

vim /etc/frr/daemons
将要使用的功能都改完yes

安装服务文件

install -m 644 tools/frr.service /etc/systemd/system/frr.service
systemctl enable frr
systemctl start frr
#查看服务状态
service frr status
