NODE PROTECTION FOR SEGMENT ROUTING ADJACENCY SEGMENTS

摘要

In one embodiment, a device in a segment routed network identifies an adjacency segment between the device and another device in the network. The device also identifies a merge point in the network. A first network path extends between the device and the merge point via the adjacency segment. A bypass network path that does not include the adjacency segment also extends between the device and the merge point. The device generates an interior gateway protocol (IGP) message that identifies the adjacency segment and the merge point. The device provides the IGP message to one or more other devices in the network.

1. A method, comprising:
identifying, by a device in a segment routed network, an adjacency segment between the device and another device in the network; identifying, by the device, a merge point in the network, wherein a first network path extends between the device and the merge point via the adjacency segment, and wherein a bypass network path that does not include the adjacency segment also extends between the device and the merge point; generating, by the device, an interior gateway protocol (IGP) message that identifies the adjacency segment and the merge point; and providing, by the device, the IGP message to one or more other devices in the network.
