    摘要: A connection between network nodes in a communication network is backed up. A failover label-switched path (LSP) is created starting at a first network node of a connection and ending 5 at the second node of the connection, while bypassing the protected connection. In the event of connection failure, data is transmitted through the failover LSP. A network operator can selectively protect different types of data by using filters that bind one or more types of traffic received over one or more interfaces to different failover LSPs.

    摘要: A router receives destination address information for a packet and determines, among entries in a first forwarding table, a closest match for the received destination address information. The router receives a pointer to a second forwarding table in accordance with the closest match determined in the first forwarding table and determines, among entries in the second forwarding table, a closest match for the received destination address information.

    摘要: A routing device may be connected to multiple spoke site networks, and may receive local routes from these spoke site networks. The routing device may include routing information and forwarding information. The routing device may update the routing information to include the local routes, and selectively generate the forwarding information to exclude the local routes. The routing device may associate labels with the local routes and advertise the labels and local routes to other routing devices. The labels may be associated with interfaces of the routing device or access links that connect the routing device to a spoke site network, and the associations of labels with interfaces or access links may be stored in the forwarding information. The routing device may forward received packets that include the labels according to the labels, and may forward other received packets according to the routes within the forwarding information.
