Usage guidelines
This command enables LDP to detect and terminate LSP loops. LDP loop detection uses one of the
following methods:
Hop count. For more information, see "maxhops."
•
Path vector. For more information, see "pv-limit."
•
Use LDP loop detection only in networks with 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.
Examples
# Enable LDP loop detection for the public network.
<Sysname> system-view
[Sysname] mpls ldp
[Sysname-ldp] loop-detect
