ospf timer ldp-sync hold-max-cost

Function

The ospf timer ldp-sync hold-max-cost command sets the interval at which OSPF advertises the maximum cost through LSAs.

The undo ospf timer ldp-sync hold-max-cost command restores the default interval.

By default, OSPF always advertises the maximum metric in LSAs on the local device before an LDP session is reestablished.

Format

ospf timer ldp-sync hold-max-cost { value | infinite }

undo ospf timer ldp-sync hold-max-cost

Parameters

Parameter	Description	Value
value	Specifies the interval at which OSPF LSAs are sent to advertise the maximum metric on the local device.	The value is an integer ranging from 0 to 65535, in seconds.
infinite	Indicates that OSPF always advertises the maximum metric in LSAs on the local device before an LDP session and an LDP adjacency are reestablished.	-

Usage Guidelines

Usage Scenario

When the primary LSP recovers from a fault, you can use the ospf timer ldp-sync hold-max-cost command to set the interval during which traffic is still transmitted along the backup LSP before the LDP session and LDP adjacency of the primary LSP are reestablished.

You can choose different parameters as required.

When OSPF carries only LDP services, set infinite to ensure that the OSPF route is always consistent with the LDP LSP.
When OSPF carries multiple services, including LDP services, specify value to ensure that OSPF route selection and other services are normal if an LDP session or LDP adjacency for the primary LSP fails.

Precautions

If this command is run more than once, the latest configuration overrides the previous ones.

Example

# Set the interval to 8 seconds for sending OSPF LSAs to advertise the maximum metric on the local device.
