Parameter number: Maximum number of routes for the VPN instance to support, in the range 1 to 1024 for MSR20 and MSR30 series routers and 1 to 2048 for MSR50 series routers.

warn-threshold: Threshold for rejecting new routes. It is expressed in the percentage of the specified maximum number of routes for the VPN instance. It ranges from 1 to 100.

simply-alert: Specifies that when the maximum number of routes exceeds the threshold, the system still accepts routes and generates only a SYSLOG error message.

Description Use the routing-table limit command to limit the maximum number of routes in a VPN instance, preventing too many routes from being accepted a PE.

Use he undo routing-table limit command to restore the default.

The default maximum number of routes that a VPN instance supports varies by device.

Example # Specify that VPN instance vpn1 can receive up to 1,000 routes, and can receive new routes after the threshold is exceeded.
