SwitchC XGE0/0/1 VLANIF 30 100.2.1.2/24
NOTE
BFD for IS-IS cannot be used to detect the multi-hops link between Switch A and Switch C, because the
IS-IS neighbor relationship cannot be established between Switch A and Switch C.
Configuration Roadmap
The configuration roadmap is as follows:
1. Enable basic IS-IS functions on each switch.
2. Enable BFD on Switch A and Switch B.
Data Preparation
To complete the configuration, you need the following data:
l IS-IS process ID
l Area addresses of Switch A, Switch B, and Switch C
l Levels of Switch A, Switch B, and Switch C
l Name of the BFD session set up between Switch A and Switch B and the peer IP address
to be detected
l Local and remote discriminators of the BFD session set up between Switch A and Switch
B
Procedure
Step 1 Configure VLANs that interfaces belong to.
<Quidway> system-view
[Quidway] sysname SwitchA
[SwitchA] vlan batch 10
[SwitchA] interface xgigabitethernet 0/0/1
[SwitchA-XGigabitEthernet0/0/1] port hybrid pvid vlan 10
[SwitchA-XGigabitEthernet0/0/1] port hybrid untagged vlan 10
[SwitchA-XGigabitEthernet0/0/1] quit
The configurations of Switch B and Switch C are similar to the configuration of Switch A, and
are not mentioned here.
Step 2 Configure an IP address for each VLANIF interface.
[SwitchA] interface vlanif 10
[SwitchA-Vlanif10] ip address 100.1.1.1 24
[SwitchA-Vlanif10] quit
The configurations of Switch B and Switch C are similar to the configuration of Switch A, and
are not mentioned here.
Step 3 Configuration basic IS-IS functions.
# Configure Switch A.
[SwitchA] isis 1
[SwitchA-isis-1] is-level level-2
[SwitchA-isis-1] network-entity aa.1111.1111.1111.00
[SwitchA-isis-1] quit
