maximum routes
To limit the maximum number of routes in a Virtual Private Network (VPN) routing and forwarding
(VRF) instance to prevent a provider edge (PE) router from importing too many routes, use the
maximum routes command in VRF configuration mode or VRF address family configuration mode. To
remove the limit on the maximum number of routes allowed, use the no form of this command.

Command History
Usage Guidelines The maximum r

Generate a warning message when the limit value is exceeded
Generate a warning message when the warn-threshold value is reached
limit The maximum number of routes allowed in a VRF. The valid range is
fro
m 1 to 4294967295 routes.
warn-threshold The warning threshold value expressed as a percentage (from 1 to
100)
of the limit value. When the number of routes reaches the
specified percentage of the limit, a warning message is generated.
warning-only Issues a system message logging (syslog) error message when the
m
aximum number of routes allowed for a VRF exceeds the threshold.
However, additional routes are still allowed.
