Subject: link failures.

Hi All,

I have a basic question regarding link failures.Suppose that an LSR or a ROUTER for that matter has made its routng decision for some pkts and have buffered them for transmission in the output queue to be sent on a particular interface.

Now lets assume that this interface went DOWN after the pkts were queued.In this case these pkts cannot be transmitted on the interface.
There may or may not be other interfaces on which these pkts would have been transmitted, perhaps this was the best one to transmit them on.

Question: 

(1) How long is the LSR/Router gonna buffer these pkts in the output queue.Will these pkts be dropped or will they be re processed for possible transmission on other interfaces ?

Any pointers in this area are welcome.

Sincerely,
Abrar Hussain.
