Changing IS-IS 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.
These parameters are configured for all IS-IS sessions or all IS-IS sessions out of an interface; if you
change a parameter globally, the change affects all IS-IS neighbors sessions. If you change a parameter at
interface level, the change affects all IS-IS sessions on that interface.
To change parameters for all IS-IS sessions:
Step Task
1 Change parameters for all IS-IS
sessions.
To change parameters for IS-IS sessions on an interface:
Step Task
1 Change parameters for all IS-IS
sessions out of an interface.
