Guide.
RIP and static routes are advertised with the Implicit NULL label and direct routes are
advertised with an MPLS label, unless PHP is enabled.
You can control the number of labels advertised using the
command. Advertising labels for a large number of routes may increase the
advertise
required number of labels that must be allocated by LSRs. Take care to insure that the
number of labels advertised by LERs does not overwhelm the label capacity of the
LSRs.

Configuring LDP Session Timers

To configure LDP session timers, use the following command:
config mpls [ldp | targeted-ldp] [hello | keep-alive] <hold_time>
<interval_time>
LDP session timers are separately configurable for LDP and targeted LDP sessions. The
hello <hold_time> <interval_time>

message is not received from a particular neighboring LSR within the specified
, the hello-adjacency is not maintained with that neighboring LSR.
<hold_time>
The session

particular peer LSR to be maintained. If an LDP PDU is not received within the
