Changing VRRP session parameters
BFD sessions are configured with default intervals and a default role. The parameters that can be
configured are: Desired TX Interval, Required Min RX Interval, Detection Multiplier, and system role.
You can change parameters for all VRRP sessions for a particular neighbor.
