Configuring LDP loop detection 

LDP detects and terminates LSP loops in the following ways: 

•

 

Maximum hop count

—LDP adds a hop count in a label request or label mapping message. The 

hop count value increments by 1 on each LSR. When the maximum hop count is reached, LDP 

considers that a loop has occurred and terminates the establishment of the LSP. 

•

 

Path vector

—LDP adds LSR ID information in a label request or label mapping message. Each LSR 

checks whether its LSR ID is contained in the message. If it is not, the LSR adds its own LSR ID into 

the message. If it is, the LSR considers that a loop has occurred and terminates LSP establishment. 

In addition, when the number of LSR IDs in the message reaches the path vector limit, LDP also 
considers that a loop has occurred and terminates LSP establishment. 

To configure LDP loop detection: 

 

Step Command 

Remarks 

1.

 

Enter system view. 

system-view 

N/A 

2.

 

Enter LDP view or enter 

LDP-VPN instance view. 

•

 

Enter LDP view: 

mpls ldp 

•

 

Enter LDP-VPN instance view: 

a.

 

mpls ldp 

b.

 

vpn-instance

 

vpn-instance-name

 

N/A 

3.

 

Enable loop detection. 

loop-detect 

By default, loop detection is 
disabled. 
After loop detection is 

enabled, the device uses both 
the maximum hop count and 

the path vector methods to 

detect loops. 

4.

 

Specify the maximum hop 

count. 

maxhops

 

hop-number

 

By default, the maximum hop 
count is 32. 

5.

 

Specify the path vector limit. 

pv-limit

 

pv-number

 

By default, the path vector limit 
is 32. 

 

 

NOTE: 

The LDP loop detection feature is applicable only in networks comprised of devices that do not support TTL
mechanism, such as ATM switches. Do not use LDP loop detection on other networks because it only results

in extra LDP overhead. 

 

 

Configuring LDP session protection 

If two LDP peers have both a direct link and an indirect link in between, you can configure this feature to 

protect their LDP session when the direct link fails.  
LDP establishes both a Link Hello adjacency over the direct link and a Targeted Hello adjacency over the 
indirect link with the peer. When the direct link fails, LDP deletes the Link Hello adjacency but still 

maintains the Targeted Hello adjacency. In this way, the LDP session between the two peers is kept
