Default Level
2: System level
Parameters
number: Maximum number of routes for the VPN instance to support, in the range 1 to 128000..
warn-threshold: Threshold for warning. It is expressed in the maximum percentage of the number of
routes for the VPN instance. It ranges from 1 to 100. When the specified threshold is reached, the
system gives an alarm message but still allows new routes. If the number of routes received reaches
the maximum supported, no more routes will be activated..
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 by a PE.
Use the undo routing-table limit command to cancel the configured limit.
Examples
# Specify that VPN instance vpn1 can receive up to 1000 routes, and can receive new routes after the
threshold is exceeded.
