[docker]使用quaaga实现(rip ospf)实现主机间容器互通

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

MAINTAINER 谁改谁去死！

RUN apt-get update
RUN apt-get install -y quagga

quagga提供了startup-configure

这个镜像同时跑了rip和ospf

命令基本和思科的差不多

root@n2:/# vtysh

       O - OSPF, I - IS-IS, B - BGP, A - Babel,

R   10.1.1.0/24 [120/2] via 192.168.1.11, eth0, 00:07:00

测试docker连通性

docker run -it --rm busybox
/ # ping 10.1.1.1
