Release Information

Statement introduced in JUNOS Release 10.0.


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.


The bfd-liveness-detection statement and substatements are described in the JUNOS Routing Protocols Configuration Guide.

The other statements are explained separately.
