active)
1.9.d Stubs
1.9.e Load balancing (equal and unequal cost)
1.9.f Metrics
1.10 Troubleshoot OSPF (v2/v3)
1.10.a Address families (IPv4, IPv6)
1.10.b Neighbor relationship and authentication
1.10.c Network types, area types, and router types
1.10.c (i) Point-to-point, multipoint, broadcast, nonbroadcast
1.10.c (ii) Area type: backbone, normal, transit, stub, NSSA, totally stub
1.10.c (iii) Internal router, backbone router, ABR, ASBR

2019 Cisco Systems
1.11.a Address families (IPv4, IPv6)
1.11.b Neighbor relationship and authentication (next-hop, mulithop, 4-byte AS, private
AS, route refresh, synchronization, operation, peer group, states and timers)
1.11.c Path preference (attributes and best-path)
1.11.d Route reflector (excluding multiple route reflectors, confederations, dynamic
peer)
1.11.e Policies (inbound/outbound filtering, path manipulation)
2.0 VPN Technologies
2.1 Describe MPLS operations (LSR, LDP, label switching, LSP)
2.2 Describe MPLS Layer 3 VPN
2.3 Configure and verify DMVPN (single hub)
2.3.a GRE/mGRE
2.3.b NHRP

BGP)
3.4 Describe IPv6 First Hop security features (RA guard, DHCP guard, binding table, ND
inspection/snooping, source guard)
4.0 Infrastructure Services
4.1 Troubleshoot device management
