Abstract
A method and a network device for enabling communication between unnumbered interfaces are provided. A device level address may be assigned to a network device. The network device may announce the assigned device level address to a neighboring network device over a link. A corresponding device level address associated with the neighboring network device may be received over the link. A route may be stored including the received device level address associated with the neighboring network device and the link. In some implementations, the announcement of the assigned device level address is performed during protocol configuration.

1-21. (canceled)
A method comprising:
- receiving, at a network device and over a link, a device level address associated with a neighboring network device over a link;
- storing, by the network device, a route including the received device level address associated with the neighboring network device and an identifier associated with the link;
- receiving, at the network device, a request to access the neighboring network device;
- determining, by the network device, whether a routing protocol is operating correctly on the neighboring network device;
- and
- accessing, by the network device, the neighboring network device via the stored route, using the received device level address and the identifier associated with the link, when the routing protocol is not operating correctly on the neighboring network device.
A system comprising:
- a network device to:
- store a route including a device level address associated with a neighboring network device and an identifier associated with a link from the network device to the neighboring network;
- receive a request to access the neighboring network device;
- determine whether a routing protocol is operating correctly on the neighboring network device;
- and
- access the neighboring network device via the stored route, using the received device level address and the identifier associated with the link, when the routing protocol is not operating correctly on the neighboring network device.
A system comprising:
- a network device to:
- receive a plurality of device level addresses identifying neighboring network devices of the network device;
- store, based on receiving the plurality of device level addresses, indications of persistent routes between the network device and the neighboring network devices,
- the storing the indications of the persistent routes including storing the plurality of device level addresses and identifiers associated with links between the network device and the neighboring network devices;
- receive a request to access a particular neighboring network device of the neighboring network devices;
- determine whether a routing protocol is operating correctly on the particular neighboring network device;
- identify, based on the stored indications of persistent routes, a persistent route corresponding to the particular neighboring network device;
- and
- access the particular neighboring device via the identified persistent route when the routing protocol is not operating correctly on the particular neighboring network device.
