Lsp-Trigger - HP FlexFabric 12500 Command Reference Manual

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

lsp-trigger

Use lsp-trigger to configure an LSP generation policy.
Use undo lsp-trigger to restore the default.
Syntax
lsp-trigger { all | prefix-list prefix-list-name }
undo lsp-trigger
Default
LDP can only use host routes with a 32-bit mask to generate LSPs.
Views
LDP view, LDP-VPN instance view
Predefined user roles
network-admin
mdc-admin
Parameters
all: Enables LDP to use all routes to generate LSPs.
prefix-list prefix-name: Specifies an IP prefix list by its name, a case-sensitive string of 1 to 63 characters.
LDP can only use the routes permitted by the IP prefix list to generate LSPs.
Usage guidelines
The default LSP generation policy depends on the label distribution control mode.
In Ordered mode, LDP can only use the Loopback interface address routes with a 32-bit mask and
•
the routes with a 32-bit mask that match the FECs of label mappings received from downstream LSRs
to generate LSPs.
In Independent mode, LDP can use all routes with a 32-bit mask to generate LSPs.
•
After you configure an LSP generation policy, LDP uses all routes or the routes permitted by the IP prefix
list to generate LSPs, regardless of the label distribution control mode.
HP recommends that you use the default LSP generation policy.
