MPLS Commands
configure mpls
configure mpls [ldp | targeted-ldp] [hello | keep-alive] <hold_time>
<interval_time>
Description
Configures LDP session timers.
Syntax Description
Default
ldp hello <hold_time> – 15 seconds
targeted-ldp hello <hold_time> – 45 seconds
ldp hello <interval_time> – 5 seconds
targeted-ldp hello <interval_time> – 15 seconds
ldp keep-alive <hold_time> – 40 seconds
targeted-ldp keep-alive <hold_time> – 60 seconds
ldp keep-alive <interval_time> – 13 seconds
targeted-ldp keep-alive <interval_time> – 20 seconds
Usage Guidelines
LDP session timers are separately configurable for LDP and targeted LDP sessions. The
hello
<hold_time> <interval_time>
parameter specifies the amount of time (in seconds) that a hello
message received from a neighboring LSR remains valid. If a hello message is not received from a
particular neighboring LSR within the specified
hello <hold_time>
, the hello-adjacency is not
maintained with that neighboring LSR.
The session
keep-alive <hold_time> <interval_time>
parameter specifies the time (in seconds)
during which an LDP message must be received for the LDP session with a particular peer LSR to be
ldp Specifies an LDP session.
targeted-ldp Specifies a targeted LDP session.
hello <hold_time> <interval_time> The amount of time (in seconds) that a hello message received from a
neighboring LSR remains valid. If a hello message is not received from a
particular neighboring LSR within the specified hello <hold_time>, the
hello-adjacency is not maintained with that neighboring LSR. The range is 6 to
65,534.
keep-alive <hold_time>
<interval_time>
The time (in seconds) during which an LDP message must be received for the
LDP session with a particular peer LSR to be maintained. If an LDP PDU is
not received within the specified session keep-alive <interval_time>,
the corresponding LDP session is torn down.The <hold_time> range is 6 to
65,534. The <interval_time> range is 1 to 21844.
