Chapter 6: Static Routing

1. 6.1 Static Routing Implementation

   • 6.1.1 Static Routing
     • Reach Remote Networks
       • Manually
       • Dynamically
     • Why Use Static Routing?
     • When to Use Static Routes
   • 6.1.2 Types of Static Routes
     • Static Route Applications
     • Standard Static Route
     • Default Static Route
       • A default static route is a route that matches all packets.
     • Summary Static Route
     • Floating Static Route
       • Floating static routes are static routes that are used to provide a backup path to a primary static ordynamic route, in the event of a link failure.

2. 6.2 Configure Static and Default Routes

   • Configure IPv4 Static Routes
     • ip route Command
       • Router(config)# ip route network-address subnet-mask { ip-address | interface-type interface-number [ ip-address ]} [ distance ] [ name name ] [ permanent ] [ tag tag ]
     • Next-Hop Options
       • show ip route |begin gateway
       • show ip route | include C
     • Configure a Next-Hop Static Route
     • Configure a Directly Connected Static Route
       • To eliminate the recursive lookup, a directly connected static route can be implementing using the following command:
         • R1(config)# ip route 192.168.2.0 255.255.255.0 GigabitEthernet 0/1
     • Configure a Fully Specified Static Route
     • Verify a Static Route
   • Configure IPv4 Default Routes
     • Default Static Route
       • The basic command syntax of a default static route is:
         • ip route 0.0.0.0 0.0.0.0 { ip-address | exit-intf }
     • Configure a Default Static Route
     • Verify a Default Static Route
       • show ip route static
   • Configure IPv6 Static Routes
     • The ipv6 route Command
     • Next-Hop Options
     • Configure a Next-Hop Static IPv6 Route
     • Configure a Directly Connected Static IPv6 Route
     • Configure a Fully Specified Static IPv6 Route
     • Verify IPv6 Static Routes
       • Along with ping and traceroute, useful commands to verify static routes include:
         • show ipv6 route
         • show ipv6 route static
         • show ipv6 route network
   • Configure IPv6 Default Routes
     • Configure IPv6 Default Routes
     • Default Static IPv6 Route
     • Verify a Default Static Route

3. 6.3 Review of CIDR and VLSM

   • Classful Addressing
     • Classful Network Addressing
     • Classful Subnet Masks
     • Classful Routing Protocol Example
     • Classful Addressing Waste
   • CIDR
     • Classless Inter-Domain Routing
       • CDIR allows customers to receive allocation of network address space based on actual requirements, not on predefined blocks based on address class.
     • CIDR and Route Summarization
     • Static Routing CIDR Example
     • Classless Routing Protocol Example
   • VLSM
     • Fixed-Length Subnet Masking
     • Variable-Length Subnet Masking
     • VLSM in Action
     • Subnetting Subnets
     • VLSM Example

4. 6.5 Troubleshoot Static and Default Route Issues

   • Packet Processing with Static Routes
     • Static Routes and Packet Forwarding
   • Troubleshoot IPv4 Static and Default Route Configuration
     • Troubleshoot a Missing Route
     • Solve a Connectivity Problem
       • show running-config | section ip route
       • show ip route | begin gateway
       • traceroute [ip address]

5. 6.4 Configure Summary and Floating Static Routes

   • Configure IPv4 Summary Routes
     • Route Summarization
     • Calculate a Summary Route
     • Summary Static Route Example
   • Configure IPv6 Summary Routes
     • Summarize IPv6 Network Addresses
     • Calculate IPv6 Network Addresses
     • Configure an IPv6 Summary Address
   • Configure Floating Static Routes
     • Floating Static Routes
       • Some common dynamic routing protocols are:
         • EIGRP = 90
         • IGRP = 100
         • OSPF = 110
         • IS-IS = 115
         • RIP = 120
     • Configure a Floating Static Route
     • Test the Floating Static Route
