oam (Layer 2 Circuit Protocols)

Syntax

Hierarchy Level

Description

Allows you to configure bidirectional forwarding detection (BFD) and a control channel for a pseudowire, in addition to the corresponding operations and management functions to be used over that control channel. BFD provides a low resource fault detection mechanism for the continuous monitoring of the pseudowire data path and for detecting data plane failures. The control-channel statement is not applicable to Layer 2 circuit pseudowires.

Options

bfd-liveness-detection

The bfd-liveness-detection statement and substatements are described in the Junos OS Routing Protocols Library.

ping-multiplier ping-count

Specify the number of LSP ping packets to delay the virtual circuit connectivity verification (VCCV) Bidirectional Forwarding Detection (BFD) session from going down. The VCCV BFD session is signaled down only after the specified number of LSP ping packets are lost. This feature is supported for Layer 2 Circuit, Layer 2 VPN, and VPLS technologies.

The other statements are explained separately.
