Configure BFD in VLT Domain
Dell EMC Networking OS supports Bidirectional Forwarding Detection (BFD) to detect communication failures on an interface that is a
part of a VLT link aggregation group (LAG).
In VLT domain, BFD provides high availability path when there are communication failures in any one of the VLT LAG links. The VLT nodes
and top of rack (ToR) use the VLT LAG links to carry the BFD packets. When any one of the VLT LAG links connected to the ToR is
down, the BFD packets reach the VLT primary or secondary using the VLTi (ICL) link.
Sample BFD configuration in VLT domain
The following shows the sample configuration of BFD implementation in VLT environment:
