Maximum Number of Virtual Routers By Device Model

The maximum number of virtual routers you can create depends on the device model. The following table provides the maximum limits. You can double-check on your system by entering the show vrf counters command, which shows the maximum number of user-defined virtual routers for that platform not including the global virtual router. The numbers in the table below include user and global routers. For the Firepower 4100/9300, these numbers apply to native mode.

For platforms that support multi-instance capability, such as the Firepower 4100/9300, determine the maximum number of virtual routers per container instance by dividing the maximum virtual routers by the number of cores on the device, and then multiplying by the number of cores assigned to the instance, rounding down to the nearest whole number. For example, if the platform supports a maximum of 100 virtual routers, and it has 70 cores, then each core would support a maximum of 1.43 virtual routers (rounded). Thus, an instance assigned 6 cores would support 8.58 virtual routers, which rounds down to 8, and an instance assigned 10 cores would support 14.3 virtual routers (rounding down, 14).
