Quidway S6500 Series Ethernet Switches Chapter 4 Integrated IS-IS Configuration Commands
Huawei Technologies Proprietary
4-19
This command is only applicable to level-1-2 router. If the local router is a level-1-2
router and it is required to establish a correlation with the peer router on a certain level
(level-1 or level-2), this command can specify the interface to send and receive hello
packets of this level. Certainly, only one type of hello packet is sent and received on the
point-to-point link. In this way, excessive processing is avoided, and the bandwidth is
saved.
For the related commands, see is-level.
Example
# When interface Vlan-interface 10 is connected with a non-backbone router in the
same area, you can set this interface as level-1, prohibiting the sending and receiving
of level-2 hello packets.
[Quidway] interface Vlan-interface 10
[Quidway-Vlan-interface10] isis enable
[Quidway-Vlan-interface10] isis circuit-level level-1
4.1.21 isis cost
Syntax
isis cost value [ level-1 | level-2 ]
undo isis cost [ level-1 | level-2 ]
View
Interface view
Parameter
value: Specify the link cost used in the SPF calculation of corresponding level. Its range
is 0 to 63. By default, the value is 10.
level-1: indicate that the link cost corresponds to level-1.
level-2: indicate that the link cost corresponds to level-2
Description
Using isis cost command, you can configure the link cost of this interface when
performing SPF calculation. Using undo isis cost command, you can restore the
default link cost.
If neither Level 1 nor Level 2 is specified in the configuration, both level-1 and level-2
will be the default value.
The user is recommended to configure the appropriate link cost for all the interfaces.
Otherwise, the link cost in the calculation of IS-IS routes cannot reflect the link cost.
