Cisco Cisco Packet Data Gateway (PDG)
BFD Configuration Mode Commands
BFD provides a low-overhead, short duration method of detecting failures in the forwarding path between
two BGP or OSPF adjacent routers, including the interfaces, data links, and forwarding plane. BFD must be
enabled on both routers. The ASR 5000 and ASR 5500 supports BFD on Layer 3 clients only in asynchronous
mode with optional Echo functionality.
