Switch C XGE0/0/2 VLANIF 50 2.2.2.1/24
Switch C XGE0/0/1 VLANIF 10 1.1.1.2/24
Configuration Roadmap
The configuration roadmap is as follows:
1. Enable IS-IS on each switch and ensure the connectivity of the switches
2. Set the interface cost of IS-IS to control the route selection of the switches.
3. Enable global BFD.
4. Enable the BFD detection mechanism of the IS-IS process on Switch A, Switch B, and
Switch C.
5. Enable the BFD detection mechanism of the interfaces on Switch A and Switch B.
Data Preparation
To complete the configuration, you need the following data:
l Process ID of IS-IS
l Area numbers of Switch A, Switch B, and Switch C
l Interface cost of Switch A, Switch B and Switch C
l Interface number and type number of BFD enabled on Switch A and Switch B
l Minimum interval for sending the BFD packets, minimum interval for receiving the BFD
packets, and local detection multiple on Switch A and Switch B
Procedure
Step 1 Configure VLANs that interfaces belong to.
<Quidway> system-view
[Quidway] sysname Switch A
[SwitchA] vlan batch 10 20
[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
[SwitchA] interface xgigabitethernet 0/0/2
[SwitchA-XGigabitEthernet0/0/2] port hybrid pvid vlan 20
[SwitchA-XGigabitEthernet0/0/2] port hybrid untagged vlan 20
[SwitchA-XGigabitEthernet0/0/2] quit
The configurations of SwitchB and SwitchC are similar to the configuration of SwitchA, and
are not mentioned here.
Step 2 Assign an IP address to each VLANIF interface.
[SwitchA] interface vlanif 10
[SwitchA-Vlanif10] ip address 1.1.1.1 24
[SwitchA-Vlanif10] quit
[SwitchA] interface vlanif 20
[SwitchA-Vlanif20] ip address 3.3.3.1 24
[SwitchA-Vlanif20] quit
