Configuring a Time to Live

The information received from a neighbor expires after a specific amount of time (measured in seconds)
called a Time to Live (TTL). The TTL is the product of the LLDPDU transmit interval (hello) and an
integer called a multiplier. The default multiplier is 4, which results in a default TTL of 120 seconds.
Adjust the TTL value—at CONFIGURATION level or INTERFACE level—using the command
Return to the default multiplier value using the command
