Quidway S6700 Series Ethernet Switches
Configuration Guide - Reliability
Use the default values of the minimum sending interval, the minimum receiving interval, and
the local detection multiplier of a BFD control packet.
Procedure
Step 1 Add interfaces to VLANs, create VLANIF interfaces, and assign an IP address to each VLANIF
interface.
# Create a VLAN on Switch A and add the interface to the VLAN.
<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
# Create a VLANIF interface and assign an IP address to the VLANIF interface.
[SwitchA] interface vlanif 10
[SwitchA-Vlanif10] ip address 10.1.1.1 16
[SwitchA-Vlanif10] quit
The configurations of Switch B and Switch C are the same as the configuration of Switch A,
and are not mentioned here.
Step 2 Configure a reachable static route between Switch A and Switch C.
[SwitchA] ip route-static 10.2.0.0 16 10.1.1.2
The configuration of Switch C is the same as the configuration of Switch A, and is not mentioned
here.
Step 3 Configure multi-hop BFD on Switch A and Switch C.
# Create a BFD session with Switch C on Switch A.
[SwitchA] bfd
[SwitchA-bfd] quit
[SwitchA] bfd atoc bind peer-ip 10.2.1.2
[SwitchA-bfd-session-atoc] discriminator local 10
[SwitchA-bfd-session-atoc] discriminator remote 20
[SwitchA-bfd-session-atoc] commit
[SwitchA-bfd-session-atoc] quit
# Create a BFD session with Switch A on Switch C.
<Quidway> system-view
[Quidway] sysname SwitchC
[SwitchC] bfd
[SwitchC-bfd] quit
[SwitchC] bfd ctoa bind peer-ip 10.1.1.1
[SwitchC-bfd-session-ctoa] discriminator local 20
[SwitchC-bfd-session-ctoa] discriminator remote 10
[SwitchC-bfd-session-ctoa] commit
[SwitchC-bfd-session-ctoa] quit
Step 4 Verify the configuration.
After the configuration is complete, run the display bfd session command on Switch A and
Switch C, and you can find that a BFD session is set up and is in Up state.
Take Switch A for example. The display is as follows:
<SwitchA> display bfd session all verbose
