Limitations

The following limitations apply to BFD in this release:

Direct connection (single hop) networks only are supported.
BGP (Border Gateway Protocol), OSPF (Open Shortest Path First), MPLS (Multiprotocol Label Switching) and static routes act as BFD clients.
Hitless failover is supported.
The echo function is not supported.
Hardware assist BFD is supported only on standalone X460-G2 and X870 series switches.
The number of sessions handled by BFD at minimal timers (less than 100ms) varies depending on the platform type, the implementation type (H/w or S/w), and the processing load (which is influenced by other protocols being enabled or other system conditions such as software forwarding).
The following scaling limits apply to BFD hardware assist:
- Maximum 900 sessions if PTP feature not enabled.
- Maximum 425 sessions with PTP enabled.
- Maximum of 256 sessions with 3 ms transmit interval.
