Description
Configure Bidirectional Forwarding Detection (BFD) timers and authentication for aggregated Ethernet interfaces.
For an aggregated ethernet interface, you cannot configure all three configuration
options, bfd-liveness-detection, minimum-links,
and sync-reset at the same time.
Options
| holddown-interval milliseconds |
Specify a time limit, in milliseconds, indicating the time that a BFD session remains up before a state change notification is sent. If the BFD session goes down and then comes back up during the hold-down interval, the timer is restarted.
|
| local-address bfd-local-address |
Specify the loopback address or the AE interface address of the source of the BFD session. Note:
Beginning with Release 16.1R2, Junos OS checks and validates the
configured micro BFD |
| minimum-interval milliseconds |
Specify a minimum time interval after which the local routing device
transmits a BFD packet and then expects to receive a reply from the BFD
neighbor. Optionally, instead of using this statement, you can configure
the minimum transmit and receive intervals separately using the
|
| minimum-receive-interval milliseconds |
Specify the minimum time interval after which the routing device expects to receive a reply from the BFD neighbor.
|
| multiplier number |
Specify the number of BFD packets that were not received by the BFD neighbor before the originating interface is declared down.
|
| neighbor bfd-neighbor-address |
Specify the loopback address or the AE interface address of a remote destination to send BFD packets. |
| no-adaptation |
Disable the BFD adaptation. Include this statement if you do not want the BFD sessions to adapt to changing network conditions. We recommend that you do not disable BFD adaptation unless it is preferable not to have BFD adaptation enabled in your network. |
| version |
Configure the BFD version to detect (BFD version 1) or autodetect (the BFD version). Note:
The
