The TE-LSP spans one or more intervening domains located between the local domain and the remote domain. The head-end node sends a routing information request over the TE-LSP to a target node on the TE-LSP that is in the remote domain. The head end node receives routing information from the target node. The received routing information includes a list of address prefixes reachable by the target node. The head end node uses the received routing information to calculate routes reachable via the TE-LSP to the target node. The calculated routes have a next-hop interface set to be the TE-LSP. The calculated routes are inserted into a routing table of the head-end node."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Propagation of routing information in RSVP-TE for inter-domain TE-LSPs","description":"In one embodiment, a traffic engineering (TE) label switched path (LSP) is established between a head-end node in a local domain and a tail-end node in a remote domain.
