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.

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.
