Nokia 4A0-D03 Exam Objectives

Section 1: EVPN on SR Linux
Weight:
-
Explain the purpose and application of EVPN in the data center
Describe the EVPN building blocks – MP-BGP for the control plane and VXLAN for the data plane
List the benefits of EVPN in the data center
List the EVPN capabilities of SR Linux 
Explain the EVPN terminology
Examine the BGP EVPN Route Types and their usage
Review the basic EVPN operations
Configure BGP for EVPN
Configure VXLAN tunnels for EVPN

Hands-on Labs: 
  • Explore typical Leaf and Spine underlay network configuration
  • Configure a BGP route reflector for EVPN
Section 2: Layer 2 EVPN
Weight:
-
Explain the use case for L2 EVPN
Describe the L2 EVPN operations 
Configure a MAC-VRF for L2 EVPN with SR Linux CLI
Verify the details of L2-related EVPN Routes (MAC and IMET) 
Review the L2 EVPN MAC protection, MAC mobility and MAC duplication monitoring procedures
Explain the need for proxy-ARP in a L2 EVPN, and how to apply proxy-ARP to IP duplication detection (IP anti-spoofing)
Configure Proxy-ARP in a L2 EVPN

Hands-on Labs:
  • Configure a L2 EVPN MAC-VRF, verify MAC mobility and MAC duplication
  • Configure Proxy ARP for a L2 EVPN 
Section 3: L3 EVPN
Weight:
-
Explain the use case for L3 EVPN
Describe the L3 EVPN Asymmetric Model and its implementation using the EVPN MAC/IP route type 2
Describe the L3 Symmetric Model and its implementation using the EVPN IP Prefix Route Type 5
Explain the purpose of IRB interfaces and the anycast-gateway IP address
Configure both an Asymmetric and Symmetric L3 EVPN with SR Linux CLI
Configure a L3 EVPN PE-CE BGP peering and verify how BGP path attributes are propagated across the EVPN

Hands-on Labs:
  • L3 EVPN – Asymmetric model with anycast-gateway IP addresses
  • L3 EVPN – Symmetric model with host-route advertising
  • Configure a PE-CE BGP peering in the L3 EVPN
Section 4: L2 and L3 EVPN Multi-homing
Weight:
-
Describe the multi-homing use cases
Describe the 2 possible redundancy modes: All-Active and Single-Active
Explain the Ethernet Segment concept and associated LAG interfaces
