Cisco Bug: CSCvu44616 - [LAN Automation] bfd all-interfaces automation breaks adjacencies or stops them from coming up
Jun 10, 2020
- Cisco DNA Center
Known Affected Releases
Symptom: When using LAN Automation in Cisco DNA Center, on the LAN automation seed devices (primary and peer devices), Bidirectional Forwarding Detection (BFD) "bfd all-interfaces" is provisioned at the router configuration level. If there are existing routing adjacencies and BFD is not applied at the interface level, these adjacencies will be torn down. If the configuration between the seed devices is performed manually (or with templates) and no BFD configuration is configured on this interface, bfd all-interfaces at the router configuration level will cause the IS-IS adjacency between the peers to never come up. If the seed devices have existing IS-IS adjacencies without BFD at the interface level, BFD all-interfaces will cause these adjacencies to be torn down. Conditions: This was observed in Cisco DNA Center 22.214.171.124.
