38-23 max-hop-count
This command is used to configure the maximum hop count allowed for loop detection. Use the
no
form of this
command to restore the default value.
max-hop-count
VALUE
no max-hop-count
Parameters
38-24 max-path-vector
This command is used to configure the maximum path vector value allowed for loop detection. Use the
no
form of this
command to restore the default value.
mpls ldp max-path-vector
VALUE
no mpls ldp max-path-vector
Parameters
Usage Guideline
This command is used to configure LDP loop detection. The LDP loop detection
mechanism makes use of the Path Vector and Hop Count TLVs carried by the label
request and label mapping messages to detect looping LSPs.
Note:
If LDP is running, configuring loop detection will lead to LDP sessions restart.
Example
This example shows how to enable LDP loop detection.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)# mpls label protocol ldp
DXS-3600-32S(config-mpls-router)#loop-detection
VALUE
Specifies the maximum hop count allowed for loop detection. The range is 1-255.
Default
The default value is 254.
Command Mode
MPLS Router Configuration Mode.
Command Default Level
Level: 15.
Usage Guideline
The hop count value is valid with the loop detection configured. If the hop count
value in the label mapping message or the label request message of LDP is greater
than the configured value, it is deemed that a loop occurs.
Example
This example shows how to configure the maximum hop count to 30.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)# mpls label protocol ldp
DXS-3600-32S(config-mpls-router)#max-hop-count 30
VALUE
Specifies the maximum path vector value. The range is 1-255.
Default
The default value is 254.
Command Mode
MPLS Router Configuration Mode.
Command Default Level
Level: 15.
