Configure Router Ldp Interface-Parameters Keepalive - Alcatel-Lucent OmniSwitch 6850-48 Cli Reference Manual

MPLS LDP Commands

configure router ldp interface-parameters keepalive

Configures the keepalive timeout and the keepalive interval on a global (all LDP interfaces) basis or on a
per-interface basis. The keepalive timeout determines how long LDP waits to receive keepalive messages
from an LDP peer before tearing down the session with that peer. The keepalive interval determines how
often LDP sends out keepalive messages, which advertise the keepalive time.
configure router ldp interface-parameters [interface ip-intf-name] keepalive timeout factor
configure router ldp interface-parameters [interface ip-intf-name] no keepalive
Syntax Definitions
ip-intf-name
timeout
factor
Defaults
By default, the keepalive time is set to 30 seconds and the factor number is set to 3, which results in a
default keepalive interval of 10 seconds.
parameter
ip-intf-name
Platforms Supported
OmniSwitch 9000E
Usage Guidelines
•
Use the no form of this command to set the keepalive time and factor parameters to the default values
for these parameters. Note that if an interface name is specified with the no form of this command, the
default values applied are the values defined globally for all interfaces.
•
Use the optional interface ip-intf-name parameter to configure the keepalive time and interval for a
specific LDP interface. Note that the keepalive parameter values configured for an interface override
the global configuration of these values for the router.
•
When LDP is establishing a session between two peers, the keepalive time is negotiated to the lower
time value of the two peers. Once an operational value is agreed upon, the keepalive time is divided by
the factor number to determine the interval at which the peers will send each other keepalive messages.
•
If no keepalive messages are received from a peer during the keepalive time that is advertised by that
peer, the local LDP router will tear down the session.

The name of an existing LDP interface.
The keepalive timeout, in seconds. The valid range is 1–65535 seconds.
The number of keepalive messages to send during the keepalive time-
out. The valid range is 1–255. The factor number is divided into the
keepalive timeout to calculate the keepalive interval value.
