Usage Guidelines A virtual context provides virtualization at the device level, using virtual routing and forwarding (VRF),
to create multiple instances of Layer 3 routing tables. Contexts or VRFs provide segmentation across IP
addresses, allowing for overlapped address space and traffic separation.
This command enables the auto-generation of LISP (Locator ID Separation Protocol) and VRF (Virtual
Routing and Forwarding) configuration, to orchestrate the fabric overlay. The show-running
configuration command shows the virtual context configuration including the auto-generated base line
commands.
Examples
