Limited Functionality Link State Protocol Node

摘要

In one embodiment a limited functionality link state protocol node has one or two interfaces configured to send and receive link state protocol packets. In response to receiving, by the partially-participating link state protocol node on a first interface, a particular link state protocol data unit (LSP): sending the particular LSP from a second interface of the partially-participating link state protocol node without updating the local link state database when the second interface is currently participating in the link state protocol distribution; and sending an acknowledgment of the particular LSP from the first interface when the second interface is not currently participating in the link state protocol distribution.

1. A partially-participating link state protocol node, comprising:
storage configured to store a local link state database; one or two interfaces configured to send and receive link state protocol packets; and one or more processing elements configured to: (a) send a particular link state protocol data unit (LSP) from a second interface of said one or two interfaces without updating the local link state database in response to receiving the particular link state protocol data unit (LSP) on a first interface of said one or two interfaces when the second interface is currently participating in the link state protocol distribution; and (b) send an acknowledgment of the particular LSP from the first interface when said one or two interfaces consist of one interface such that there is no second interface currently participating in the link state protocol distribution.
