What's docker-simpleRouter

docker-simpleRouter is a software router based RyuBGP with LagopusSwitch.
It works as a openflow controller supporting mpBGP/MPLS-VPN in Docker-container.

deploying virtual network in Docker-container

You can deploy virtual networks as MPLS-VPN as bellow.
(not including OSPF/LDP protocols in simpleRouter)

 pc2 ---- BGP6 ---- BGP4 ---- BGP1 ---- BGP3 ---- pc1
           |         |         |         |
           \------- BGP5 ---- BGP2 ------/

          < AS65010 >        < AS65011 >

Environment

It recommends for using Ubuntu Server Edition.
LagopusSwitch has not been installed DPDK environment in simpleRouter.
Therefore, LagopusSwitch works as Raw-socket edition

As a result, deploying virtual network for MPLS-VPN like this

      (192.168.2.101)                                    (192.168.1.102)
        ↓                                                ↓
       pc2 ---- BGP6 ---- BGP4 ---- BGP1 ---- BGP3 ---- pc1
                 |         |         |         |
                 \------- BGP5 ---- BGP2 ------/

Accessing ... after starting simpleRouter

For example, you can access container 'pc1' for executing ping from pc1 to pc2

$ docker exec -it pc1 bash
root@pc1:/# ping 192.168.2.101

For example, you can access container 'BGP3' for checking show-rib

$ docker exec -it BGP3 bash
root@BGP3:~# cd simpleRouter/rest-client/
root@BGP3:~/simpleRouter/rest-client# ./get_rib.sh
