■Modifying the LDP recovery time may cause the original sessions to be reestablished. The LSPs based on the sessions will be removed and need to be reestablished.

Example # Set the LDP recovery time to 45 seconds.

<Sysname> system-view

[Sysname] mpls ldp

[Sysname-mpls-ldp] graceful-restart timer recovery 45

Parameter hop-number: Hop count, in the range 1 to 32.

Description Use the hops-countcommand to set the maximum hop count for loop detection.

Use the undo hops-countcommand to restore the default.

By default, the maximum hop count for loop detection is 32.

Note that:

■You must configure the command before enabling LDP on any interface.

■The maximum hop count dictates how fast LDP detects a loop. Adjust this argument as required.

Related command: loop-detect,path-vectors.

Example # Set the maximum hop count for loop detection to 25 for the public network LDP.

<Sysname> system-view

[Sysname] mpls ldp

[Sysname-mpls-ldp] hops-count 25

#Set the maximum hop count for loop detection to 25 for LDP instance named vpn1.

<Sysname> system-view

[Sysname] mpls ldp vpn-instance vpn1

[Sysname-mpls-ldp-vpn-instance-vpn1] hops-count 25
