(Optional) Adjusting BFD Parameters
IPv6 PIM BFD does not apply to Point-to-point (P2P) interfaces. IPv6 PIM BFD parameters include the minimum interval for sending and receiving PIM BFD packets and the local detection multiplier. BFD negotiates actual parameter values of detection packets based on configurations on the two ends.
Context
If there is no special requirement for the detection period and the link is stable, you are recommended to configure the same parameter values for the routing devices of the same performance on the shared network segment.
Perform the following steps on the routers that have set up a PIM neighbor relationship:
Procedure
- Run system-view
The system view is displayed.
- Run interface interface-type interface-number
The interface view is displayed.
- Run pim ipv6 bfd { min-tx-interval min-tx-interval-val | min-rx-interval min-rx-interval-val | detect-multiplier multiplier-value *}
The minimum sending interval, minimum receiving interval, and local detection multiplier of BFD packets are configured.
The default parameter values are defined uniformly in the BFD module.
The two ends negotiate the actual sending interval and receiving interval, and detection period of PIM IPv6 BFD packets based on the following negotiation mechanism:- Actual sending interval and receiving interval of PIM IPv6 BFD packets:
- Actual sending interval = max (local min-tx-interval, remote min-rx-interval)
- Actual receiving interval = max (remote min-tx-interval, local min-rx-interval)
Actual detection period = Remote detect-multiplier x max (remote min-tx-interval, local min-rx-interval)
