What is a best practice the administrator should implement to reduce CPU processing on the switches if a BFD neighbor fails?

An administrator is managing a pair of core AOS-CX switches configured for VSX. Connected to this core are pairs of aggregation layer AOS-CX switches configured for VSX. OSPF is running between the aggregation and core layers. To speed up OSPF convergence, the administrator has configured BFD between the core and aggregation switches.

A . Disable ICMP redirects
B. Implement graceful restart
C. Increase the BFD echo timers
D. Increase the VSX keepalive timer
