Virtual Routing and Forwarding (VRF) | 1031
VRF Configuration
The VRF configuration tasks are:
1. Load the VRF CAM Profile
2. Enable VRF
3. Assign an Interface to a VRF
You can also:
• View VRF instance information
• Connect an OSPF process to a VRF instance
• Configure VRRP on a VRF Interface
Load the VRF CAM Profile
On an E-series Terascale platform, select the IPv4 or IPv6 CAM profile used to support VRF and reload
the system to activate the profile.
On an E-series Exascale platform, configure the CAM size used to support VRF. Then enable VRF
microcode for use with the CAM profile 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.
Note: Starting in FTOS 8.4.2.1, when VRF microcode is loaded on an E-Series ExaScale or TeraScale
router, the
ip vrf [ default-vlan | vrf-name] command is deprecated, and is replaced by the ip vrf vrf-name
vrf-id command. The ip vrf-vlan-block, start-vlan-id default-vrf, and start-vlan-id vlan-start-id commands are
also deprecated.
