vBNG Initial Configuration by cloud-init
...
Subscribers are usually configured by calls to bbs-edge-restconf-server directly from ONAP. In case you would like to test this functionality you can of course trigger this by calling this directly with curl to the floating IP, TCP port 5000 of the vbng instance:
...
Important parameters are: "remote_id":"AC9.000.990.001","s_vlan":10,"c_vlan":333 .Of course the values configured must match what the OLT/ONT in the Lab sends. The DHCP authentication is done only on the correct value of remote_id. Once successfully authenticated and given a lease by DHCP, dataplane configuration is delegated to a host process . It is subscribing to the message queue and configuring by publishing a message to the queue. The host process is consuming the message from the queue and configures subscribers dataplane with the help of those two scripts:
