We are planning to implement BFD on LAG using X670 Switches and CISCO Nexus. I couldn't find any reference of Micro BFD sessions or BFD on LAG on XOS 15.X or 21.X. Do you now if it is supported?
I knew it can be configured , but as per rfc72130, BFD over a LAG has a specific operation (Micro-BFD Sessions). On other vendors I found this implementations supported on the documentation, but I could not find any reference on XOS docs. Do you know if there any document were I can find it?
I’ve seen same topology working between 2 routers (same vendor), but they use BFD Single session. It also works, but when there is another vendor on the other site, it must be running independent micro BFD sessions to monitor the status of individual member links. Have you tested this scenario with other vendor equipment?. Thanks in advance
Afaik we do no support rfc7130 (BFD on every single-link of a LAG). For interoperability with other vendor supporting it, you might need to turn it off on the other side. If the plan is to shut the LAG once a member fails, you can configure it on your LAG (minimum-active).
