ANTA catalog for BFD tests
VerifyBFDPeersHealth ¶
Verifies the health of IPv4 BFD peers across all VRFs.
It checks that no BFD peer is in the down state and that the discriminator value of the remote system is not zero.
Optionally, it can also verify that BFD peers have not been down before a specified threshold of hours.
Expected Results
- Success: The test will pass if all IPv4 BFD peers are up, the discriminator value of each remote system is non-zero, and the last downtime of each peer is above the defined threshold.
- Failure: The test will fail if any IPv4 BFD peer is down, the discriminator value of any remote system is zero, or the last downtime of any peer is below the defined threshold.
Examples
anta.tests.bfd:
- VerifyBFDPeersHealth:
down_threshold: 2
Inputs¶
Name | Type | Description | Default |
---|---|---|---|
down_threshold |
int | None
|
Optional down threshold in hours to check if a BFD peer was down before those hours or not.

VerifyBFDPeersIntervals ¶
Verifies the timers of the IPv4 BFD peers in the specified VRF.
Expected Results
- Success: The test will pass if the timers of the IPv4 BFD peers are correct in the specified VRF.
- Failure: The test will fail if the IPv4 BFD peers are not found or their timers are incorrect in the specified VRF.
