hot-standby (Protocols Layer 2 Circuit)


Hierarchy Level


Configure the pseudowire to the specified backup neighbor as the hot-standby. When you configure this statement, traffic flows over both the active and hot-standby pseudowires to the backup device (either a CE device or PE router). The backup device drops the traffic from the hot-standby pseudowire, unless the active pseudowire fails. If the active pseudowire fails, the backup device automatically switches to the hot-standby pseudowire.

Configure the hot-standby statement on routers that have both active and standby virtual circuits. Generally, these are access routers. On provider edge routers, configure the hot-standby-vc-on' statement to indicate that a hot-standby pseudowire is desired upon arrival of a PW_FWD_STDBY status-TLV.
