摘要： Disclosed herein are system, method, and computer program product aspects for multiple instance Intermediate System to Intermediate System (IS-IS or ISIS) for a multi-area fabric. A network area in a multi-area fabric includes one or more network nodes and a boundary node shared with an other network area of the multi-area fabric outside of the network area. The boundary node can include a first ISIS instance associated with the network area and a second ISIS instance associated with the other network area. The second ISIS instance can be configured to pass information associated with the other network area to the first ISIS instance.

摘要： Provided herein are systems and methods for managing redistribution and remapping of multicast services between networks in a multi-area network. Multicast streams can be sent through networks from a source node towards a boundary node. The boundary node can receive the multicast stream, remap a source node identifier and service instance identifier, and forward the multicast stream into a second network. The boundary node can receive a route for the multicast stream. The route can be installed in a link-state database and can be used to send the multicast stream through the multi-area network from the source node to a destination node.
