The isis ppp-osicp-check command enables OSICP negotiation check on a PPP interface. The negotiation status can affect IS-IS interface status.
The undo isis ppp-osicp-check command restores the default setting.
By default, IS-IS does not check OSICP status of PPP.
By default, OSCIP status of PPP does not affect IS-IS interface status.
After this command is configured, OSI network negotiation status of PPP can affect IS-IS interface status. When PPP senses that the OSI network fails, the link status of the IS-IS interface turns Down and the route to the network segment where the interface resides is not advertised through LSP.
PrecautionsThis command applies to only PPP interfaces. For other point-to-point interfaces, this command is invalid.
