Define VRFs CUST-A and CUST-B on a single CE-style router. Bind one interface to each VRF; demonstrate that the two customers' routing tables are isolated even though they share the device.

Scenario
VRF-Lite is "MPLS-VPN without MPLS" — the per-VRF routing table separation, but no PE-PE label-switched path. Use cases: - Multi-tenant edge: one router serves two customers; their RIBs must not leak. - Management-plane separation: a MGMT VRF carries SSH/SNMP/syslog independently of user data. - Pre-MPLS L3VPN staging: define VRFs on CEs first; add MP-BGP later. In this lab the same physical router carries two customer-facing interfaces. Each is bound to its own VRF; show ip route vrf confirms isolation.

What you will do
Define two VRFs:
ip vrf CUST-A(with RD65001:1) andip vrf CUST-B(with RD65001:2).Bind Gi0/0 to VRF
CUST-A(10.0.0.1/24) and Gi0/1 to VRFCUST-B(also10.0.0.1/24— same prefix in different VRFs is fine).
