[GTER] Regular updates, Triggered updates e Hold down timers

[Hermenegildo Pimenta]

Por favor me expliquem a aparente incoerência dessas definições:

TRIGGERED UPDATES:
A triggered update is sent immediately in response to a change in the
network. The router detecting the change immediately sends an update message
to adjacent routers.

HOLD DOWN TIMERS:
Hold-down timers force routers to hold any changes for a period of time.


Outra coisa, qual a diferença entre REGULAR UPDATES e TRIGGERED UPDATES?


Obrigado.
