Description
Configure node detection to enable bfd-liveness-detection in a multihomed environment. Node detection monitors
the liveness of EVPN BGP peers using Bidirectional Forwarding Detection (BFD) protocol.
Configure one of the peers to take action to forward traffic through
the network based on the status of the BGP and BFD sessions. The two options for the
action configuration are turning the interface lasers off and
triggering node isolation. When the action is turning the lasers off,
the lasers are off for the ESI LAG interfaces during core isolation. The trigger node
isolation action puts the ESI LAG interfaces in a link-down state.
Each option for the action configuration also requires additional
configuration.
-
The
laser-offaction requires that asynchronous-notification be configured on the ESI-LAG interfaces.
-
The
trigger-node-isolationaction requires a network-isolation profile and a service-tracking-action link-down configuration that brings the interface down on core-isolation.
The BFD session can run over standard interfaces or over the management interfaces between the EVPN BGP peers.
Junos OS Evolved platforms do not support BFD over management ports.
Options
| action |
Configure the isolation action only on one device and not both. The isolation action determines how to implement the core isolation.

| next-hop |
