LDP session retry timer

Hi. From the cisco press I read:

If the LDP peers agree on the session parameters, they keep the TCP connection between them. If

not, they retry to create the LDP session between them, but at a throttled rate. In Cisco IOS, the

LDP backoff command controls this throttling rate:

mpls ldp backoff initial-backoff maximum-backoff

The initial-backoff parameter is a value between 5 and 2,147,483, with a default of 15 seconds.

The maximum-backoff is a value between 5 and 2,147,483, with a default of 120 seconds. This

command slows down the LDP session setup attempts of two LDP LSRs, when the two

neighboring LDP peers are incompatible in terms of the parameters they exchange. If the session

setup attempt fails, the next attempts are undertaken at an exponentially increased time, until the

maximum backoff time is reached.

And what then? After maximum backoff time is reached?
