The default IS-IS network type is point-to-point so a DIS is not elected

A DIS is elected between the IS-IS neighbors and the elected DIS is pre-empted if router with a higher system ID is connected

The area, levels, and interface MTU parameters must match, and system MTU must be unique for two IS-IS routers to become adjacent

Faster IS-IS hello and dead timers increase bandwidth and CPU use, and may cause instability

The IS-IS hello and dead timers should be tuned to detect failures as quickly as possible

A DIS is elected between the IS-IS neighbors and the elected Dis is pre-empted if a router with a lower system ID is connected

The hello and dead timers must match for two IS-IS routers to become adjacent
