使用quaaga实现(rip ospf)实现主机间容器互通
- n1设置
brctl addbr br0
ip a a 10.1.1.1/24 br0
ip a a 10.1.1.1/24 dev br0
ip l s dev br0 up
systemctl stop docker
dockerd -b=br0
docker run -itd --name=router --privileged --net=host georce/router
- n2设置
brctl addbr br0
ip a a 20.1.1.1/24 br0
ip a a 20.1.1.1/24 dev br0
ip l s dev br0 up
systemctl stop docker
dockerd -b=br0
docker run -itd --name=router --privileged --net=host georce/router
georce/router的dockerfile

quagga提供了startup-configure
这个镜像同时跑了rip和ospf
