Parameters timeout — Configures the time interval, expressed in seconds, that LDP waits before tearing down
the session.
Values 3 — 65535
factor — Specifies the number of keepalive messages, expressed as a decimal integer, that should be
sent on an idle LDP session in the keepalive timeout interval.
Values 1 — 255
local-lsr-id
Syntax local-lsr-id {system | interface}
no local-lsr-id
Context config>router>ldp>interface-parameters>interface
Description This command enables the use of the address of the local LDP interface as the LSR-ID to establish a
link LDP adjacency and session with a directly connected LDP peer.
By default, the LDP session uses the system interface address as the LSR-ID unless explicitly
configured using the above command. Note however that the system interface must always be
configured on the router or the LDP protocol will not come up on the node. There is no requirement
to include it in any routing protocol though.
At initial configuration, the LDP session to the peer will remain down while the interface is down.
If the user changes the LSR-ID on the fly between system and interface values while the LDP session
is up, LDP will immediately tear down the session and will attempt to re-establish it using the new
LSR-ID.
If the interface used as LSR-ID goes down, then the LDP session goes down.
Note that when the interface option is selected, the transport connection (TCP) for the link LDP
session will also use the address of the local LDP interface as the transport address. If system is the
value configured under the command configure>router>ldp>interface-
parameters>interface>transport-address it will be overridden.
The no form of this command returns to the default behavior in which case the system interface
address is used as the LSR-ID.
Default system
local-lsr-id
Syntax local-lsr-id interface-name
no local-lsr-id
Context config>router>ldp>targeted-session>peer
Description This command enables the use the use of the address of a specific interface as the LSR-ID for the
hello adjacency of a T-LDP session. The interface can be a regular interface or a loopback interface,
including the system interface.
