Configuration Guide - IP Routing
IS-IS is required to select a DIS on a broadcast network. Configure the DIS priorities of IS-IS
interfaces so that the interface with the highest priority will be selected as the DIS.
The network types of the IS-IS interfaces on both ends of a link must be the same; otherwise,
the IS-IS neighbor relationship cannot be established between the two interfaces. For example,
if the type of an interface on a peer device is P2P, you can configure the type of an interface on
the local device to P2P so that an IS-IS neighbor relationship can be established between the
two devices.
IS-IS on a P2P network is not required to select a DIS. Therefore, you do not need to configure
DIS priorities. To ensure the reliability of P2P links, configure IS-IS to use the three-way
handshake mode for IS-IS neighbor relationship establishment so that faults on a unidirectional
link can be detected.

Configure the DIS priority of an IS-IS interface.
1.
Run:
system-view
The system view is displayed.
2.
Run:
interface interface-type interface-number
The interface view is displayed.
3.
Run:
isis dis-priority priority [ level-1 | level-2 ]
The DIS priority is configured on the interface. The greater the value, the higher the
priority.
Configure the network type of an IS-IS interface.
1.
Run:
system-view
The system view is displayed.
2.
Run:
interface interface-type interface-number
The interface view is displayed.
3.
Run:
isis circuit-type p2p
The network type of the interface is set to P2P.
The network type of an interface is determined by the physical type of the interface
by default.
When the network type of an IS-IS interface changes, interface configurations change
accordingly.
– After a broadcast interface is configured as a P2P interface using the isis circuit-
type p2p command, 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
