Setting the LDP Hello Interval and Hold Timeout values
2
The source ip-address option specifies the IP address of any interface. This address is used as
the destination address for the echo reply address. The default address is the LSR ID.
timeout msec
The timeout msec option specifies an interval in milliseconds for the echo request message.
The default timeout is five seconds. The maximum timeout value is five minutes.
nexthop ipv4 address
The nexthop specifies the nexthop IPv4 address to send the OAM request to.
Modes This command operates in all modes.
Usage guidelines You can specify the next hop IPv4 address used to send the traceroute request. If there is no
matching interface for the specified IPv4 address, the traceroute request fails. When an address
that does not match the outgoing path for the tunnel is given, following error message appears as
response:
Traceroute fails: LDP next-hop does not exist.
This is also applicable to the ping mpls ldp command.

Setting the LDP Hello Interval and Hold Timeout values
The LDP Hello interval and Hello Hold Timeout timers are used to establish Hello Adjacency
between peers. The Hello Interval is the time period between which the LSR sends out Hello
messages and the Hello Hold Timeout value is the amount of time that the sending LSR maintains
its record of Hellos from the receiving LSR without receipt of another Hello message.
The Hello interval and Hello Hold Timeout timer values can be obtained from the global default
values, configured globally on a router, or in the case of the Hello Hold Timeout timer configured
per-interface. When configuring these values the following constraints must be followed:
• The Hello Interval value must be < 32767
• The Hello Hold Timeout value must be <65535
• The Hello Hold Timeout value must be >= 2 * Hello Interval value
As described in the following sections, values can be set that determine the values used on the
configured router and values sent to adjacent peers for their configuration:
• Setting the LDP Hello Interval and Hold Timeout Values
• Setting the LDP Hold Time Sent to Adjacent LSRs
• Determining the LDP Hold Time on an MPLS Interface
