Configure BFD Policies

You can bind a BFD template to an interface belonging to a virtual router, or to a source and destination address pair.

Before you begin

Procedure

Step 1

From the Devices > Device Management page, edit the virtual-router supported device. Navigate to Routing.

Step 2

From the drop-down list, select the desired virtual router, and then click BFD.

Step 3

To configure a BFD on the interface, click the Single-Hop tab or Multi-Hop tab.

Note

For a single-hop policy, the BFD template is configured on an interface; for a multi-hop policy, the BFD template is configured on a source and destination address pair.

Step 4

Click Add. To modify the configured BFD policy, click Edit (edit icon).

Note

When you edit the interface mapping with BFD template to replace it with a new BFD template, the management center uses a no command to remove the template mapping from interface and applies the new template to the interface which causes a BFD flap which may also lead to an OSPFv2, OSPFv3, or BGP flap. However, if the BFD intervals are higher, the BFD flap might not occur. Alternatively, to avoid the flapping, you can delete the existing BFD template mapping; deploy the interface, and then add the new BFD template to the interface and deploy the configuration.
