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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Shortest path bridging (SPB) multi area","description":"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.
