Abstract

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.
