Routing Protocols

Internal Protocols

RIP (v1)

      • Max hop count of 15
      • Routing table updates every 30 seconds, and the WHOLE TABLE
      • No VLSM (CIDR)
      • No authenticiation

RIP v2

      • Yes VLSM
      • Authentication added

IGRP (Cisco proprietary)

OSPF

      • Noisy boot HELO packets
      • then LSAs to converge
      • Metric is COST not HOPS
      • Authentication
      • Prevents loops
      • Detect and corrects link errors/failurs
      • Converges immediately
      • v3 supports IPv6
      • Area 0 is the backbone (or only) layer, to divide routers into smaller areas for fast convergence and small routing tables

IS-IS

      • Link-state proto
      • IPv6 Native from its creation
      • ISP standard router
      • Multi-pathing!!!!!

Exterior Protocols

EIGRP

      • Distance-vector

BGP

      • Ties ASs together
