Hi
We have a connection from on-premises to Azure via the ExpressRoute virtual router, with BFD enabled. The BFD interval is set to 1000ms on the on-premises side and 300ms on the Azure side. However, the BGP session is frequently resetting due to BFD being down. Can anyone suggest a solution to stabilize this link?
regards,

Why you use mismatch interval in each side?

Do mismatch intervals lead to any issues with the link?
