NOTE
Some vendors also use the terms Multi-VRF CE or VRF-Lite for this technology.
Configuring Multi-VRF
A Multi-VRF instance can be configured on:
• Untagged physical ports -Only applies to SX chassis-based systems. It is recommended that these
ports be configured route-only to prevent leaking of switching traffic if two interfaces in the same
vlan are configured with different VRFs.
• Virtual interfaces
• Loopback interfaces
• Tunnel interfaces - The tunnel can belong to any user-defined VRF, but the tunnel source and
tunnel destination are restricted to the default VRF.
To configure Multi-VRF, you need to perform the following:
• Configure VRF-related system-max values.
• Configure VRF instances.
• Configure a Route Distinguisher (RD) for new VRF instance.
• Configure an IPv4 or IPv6 Address Family (AF) for new VRF instance.
• Configure routing protocols for new Multi-VRF instance.
• Assign VRF instances to Layer 3 interfaces.
