on a P2P link, and various IS-IS authentication modes. Consequently, other
configurations such as the DIS priority, DIS name, and interval for sending CSNPs
on a broadcast network become invalid.
– After the undo isis circuit-type command is run to restore the network type, the
default settings are restored for the interval for sending Hello packets, the number
of Hello packets that IS-IS fails to receive from a neighbor before the neighbor is
declared Down, interval for retransmitting LSPs on a P2P link, various IS-IS
authentication modes, DIS priority, and interval for sending CSNPs on a broadcast
network.
Set the negotiation mode in which P2P neighbor relationships can be set up.
1. Run:
system-view
The system view is displayed.
2. Run:
interface interface-type interface-number
The interface view is displayed.
3. Run:
isis ppp-negotiation { 2-way | 3-way [ only ] }
The negotiation mode is specified on the interface.
By default, the 3-way handshake negotiation mode is adopted.
The isis ppp-negotiation command can only be used for the establishment of the
neighbor relationships on P2P links. In the case of a broadcast link, you can run the
isis circuit-type p2p command to set the link type to P2P, and then run the isis ppp-
negotiation command to set the negotiation mode for the establishment of the
neighbor relationship.
Configure OSICP negotiation check on PPP interfaces.
1. Run:
system-view
The system view is displayed.
2. Run:
interface interface-type interface-number
The interface view is displayed.
3. Run:
isis ppp-osicp-check
The OSICP negotiation status is checked on a PPP interface.
By default, the OSICP negotiation status of a PPP interface does not affect the status
of an IS-IS interface.
The isis ppp-osicp-check command is applicable only to PPP interfaces. This
command is invalid for other P2P interfaces.
After this command is run, the OSICP negotiation status of a PPP interface affects the
status of an IS-IS interface. When PPP detects that the OSI network fails, the link
