E120 and E320 System Maximums
The following tables provide system maximums for the E120 router and the E320
router.
General System Maximums
Table 8 lists some general system maximums for the E120 router and the E320
router. The following notes are referred to in Table 8:
1. The maximum number applies to any combination of VRs and VRFs. The
2. The maximum of 3000 VRs and VRFs can be achieved only with the SRP-120
