ospf timer ldp-sync hold-down

Function

The ospf timer ldp-sync hold-down command sets the interval during which an interface waits for creating an LDP session and an LDP adjacency before setting up the OSPF neighbor relationship.

The undo ospf timer ldp-sync hold-down command restores the default configuration.

By default, the interval is 10 seconds.

Usage Guidelines

Usage Scenario

If an active link between two devices enabled with LDP and OSPF synchronization recovers from a fault, the OSPF module enters the Hold-down state and starts a Hold-down timer. This setting allows an interface to create an LDP session and an LDP adjacency before setting up an OSPF neighbor relationship. Traffic can switch back to the active link over a reachable OSPF route for an established LDP LSP.

The ospf timer ldp-sync hold-down command sets the Hold-down timer value.

Example

# Set the interval to 15 seconds, during which an interface waits for creating an LDP session and an LDP adjacency before setting up the OSPF neighbor relationship.
