Discovering a topology—transparent zone
A network node used to discover a topology-transparent zone (TTZ). In one example embodiment, the network node may obtain a TTZ identifier (ID) that is uniquely associated with the TTZ. Additionally, the network node may identify a link connected to a second network node that is also assigned the TTZ ID. In response to the command to initiate discovering the TTZ, the network node may generate a router information (RI) link-state advertisement (LSA) that comprises the TTZ ID and may distribute the RI LSA to the second network node using the link. In another example embodiment, the network node may not be configured as a TTZ edge node and may receive an RI LSA comprising the TTZ ID. The network node may store at least a portion of the information within the RI LSA and may flood the RI LSA using a plurality of links.
