3.2 Layer 3

Layer 3 is about path selection. A router receives a packet, checks a table or policy, and chooses a next hop. ENCOR wants you to understand why the router chose that path and how to change the decision safely.

Study order

  1. EIGRP vs OSPF routing concepts
  2. OSPFv2 and OSPFv3 simple environments
  3. eBGP between directly connected neighbors
  4. Policy-based routing

Objectives

  1. 3.2.a Compare routing concepts of EIGRP and OSPF (advanced distance vector vs. link state, load balancing, path selection, path operations, metrics, and area types)
  2. 3.2.b Configure simple OSPFv2/v3 environments, including multiple normal areas, summarization, and filtering (neighbor adjacency, point-to-point, and broadcast network types, and passive-interface)
  3. 3.2.c Configure and verify eBGP between directly connected neighbors (best path selection algorithm and neighbor relationships)
  4. 3.2.d Describe policy-based routing
