Constructing a topology-transparent zone
A network node used to construct a topology-transparent zone (TTZ). The network node may obtain a TTZ identifier (ID) that is uniquely associated with a TTZ. Additionally, the network node may obtain a first link that couples the network node to a second network node that is also assigned the TTZ ID and a second link that couples the network node to a third network node that is not assigned the TTZ ID. The network node may generate a router information (RI) link-state advertisement (LSA) that indicates whether the network node is a TTZ edge node or a TTZ internal node and that indicates the TTZ associated with the TTZ. The network node may distribute the RI LSA to the second network node that is also assigned the TTZ ID using the first link.
