FIGURE 38 Example high-level Multi-VRF topology
A Multi-VRF instance can be congured on any of the following:
• Platforms that support untagged physical ports - Applies only to FastIron SX series chassis-based systems, the Brocade ICX
7750, and the Brocade ICX 7450; untagged physical ports are not supported on the Brocade ICX 6610, ICX 6650, and FCX
series. It is recommended that these ports be congured "route-only" to prevent the leaking of switching trac if two interfaces
in the same VLAN are congured with dierent VRFs.
• Virtual interfaces
• Loopback interfaces
• Tunnel interfaces - The tunnel can belong to any user-dened VRF, but the tunnel source and tunnel destination are restricted to
the default VRF.
A Multi-VRF instance cannot be congured on any of the following:
• Physical interfaces
• Management interfaces
To congure Multi-VRF, perform the following steps:
• Congure VRF-related system-max values.
• Congure VRF instances.
