IP Services are support systems for the routed network. They are not optional details: bad time breaks logs and certificates, bad NAT breaks return traffic, bad first-hop redundancy breaks hosts, and bad multicast breaks one-to-many traffic in ways unicast troubleshooting will not explain.

Study order

  1. NTP and PTP configuration interpretation
  2. NAT and PAT
  3. HSRP and VRRP
  4. Multicast protocols

Objectives

  1. 3.3.a Interpret network time protocol configurations such as NTP and PTP
  2. 3.3.b Configure NAT/PAT
  3. 3.3.c Configure first hop redundancy protocols, such as HSRP, VRRP
  4. 3.3.d Describe multicast protocols, such as RPF check, PIM SM, IGMP v2/v3, SSM, bidir, and MSDP
