The ingress-lsp trigger command specifies a routing policy to control the creation of ingress LSPs based on labeled BGP IPv4 routes.
The undo ingress-lsp trigger command restores the default setting.
By default, ingress LSPs are created based on all received BGP labeled routes.
| Parameter | Description | Value |
|---|---|---|
| route-policy route-policy-name | Specifies the name of a routing policy to be used to create ingress LSPs based on BGP labeled routes. |
The name is a string of 1 to 40 case-sensitive characters, with spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string. |
Usage Scenario
In a MAN where the hybrid access mode is used, a large number of BGP labeled routes are used to establish end-to-end LSPs. On certain intermediate nodes where VPN services do not need to be supported, excessive ingress LSPs are created, causing the waste of network resources. In this case, you can run the ingress-lsp trigger command to create ingress LSPs based on a routing policy to save network resources.
Configuration Impact
If the ingress-lsp trigger command is run more than once, the latest configuration overrides the previous ones.
Follow-up Procedure
If the routing policy specified in the ingress-lsp trigger command does not exist, you need to configure the routing policy by using the route-policy command.
Precautions
Creating a route-policy before it is referenced is recommended. By default, nonexistent route-policies cannot be referenced using the command. If the route-policy nonexistent-config-check disable command is run in the system view and a nonexistent route-policy is referenced using the current command, ingress LSPs are established for all labeled routes.
