Virtual Routing and Forwarding (VRF) | 1113
• On an E-Series Exascale platform, use the cam-profile command to set the CAM size. Then select and
enable VRF microcode for use with the VRF CAM-profile template, and reload the system to activate
the profile. You can set the CAM size to 40M (default) which supports both IPv4 and IPv6 or 10M
which supports only IPv4.
Table 57-2 and Table 57-3 each show the required CAM settings for IPv4 and IPv6.
Note: Any physical (port or port channel) or VLAN interface assigned to a VRF uses two CAM entries
instead of one for each route and host entry.
Note: VRF is supported in single CAM cards only.

tables remain at default values. For more information on the CAM and CAM profiling, refer to Chapter 11,
