Configuration Roadmap
The configuration roadmap is as follows:
1. Create VLAN 13 on Switch A and Switch B.
2. Configure XGE 0/0/1 interfaces on Switch A and Switch B as hybrid interfaces.
3. Create VLANIF 13 on Switch A and Switch B and set their IP address.
4. Create a BFD session on Switch A to detect the link between Switch A and Switch B.
5. Create a BFD session on Switch B to detect the link between Switch B and Switch A.
Data Preparation
To complete the configuration, you need the following data:
l Numbers of VLANIF interfaces bound to BFD sessions
l IP addresses of VLANIF interfaces
l Local and remote discriminators of BFD sessions
Default values of minimum intervals for sending BFD control packets, minimum intervals for
receiving BFD control packets, and local detection multipliers
Procedure
Step 1 On Switch A and Switch B, create VLAN 13, configure XGE 0/0/1 interfaces as hybrid
interfaces, and add XGE 0/0/1 interfaces to VLAN 13.
