1. A method comprising:
- identifying for a new node added to a communications network a plurality of existing network nodes respectively connected to one of a plurality of ports of the new node and capable of implementing a particular routing protocol;
selecting one of the identified existing network nodes to serve as a designated forwarder (“
DF”
) for the new node;
closing all of the ports of the new node except for the port to which the DF is connected;
performing a power on auto provisioning (“
PoAP”
) procedure in connection with the new node; and
subsequent to the POAP procedure, opening the closed ports of the new node to which the identified existing network nodes are connected,wherein the communications network is arranged in accordance with a spine-leaf topology and the new node comprises a leaf node and each of the existing network nodes comprises a spine node.
