Static routing

Static routing

1. It's critical to any data network

   • Because
     • Transfer information via an internetwork from source to destination

2. Remote network range

   • Manually
     • are manually entered into the route table via static routes
   • Dynamically
     • are automatically discovered using a dynamic routing protocol

3. Main uses

   • Makes it easier to maintain the routing table
   • Provides routing to and from internal route networks
   • Uses a single default route to represent a route to any network that does not have a more specific match

4. Static route applications

   • Connect to a more specific network
   • Connect an internal route router
   • Summarize routing table entries
   • Create a backup path

5. Types of static routes

   • Standard static route
   • Default static route
   • Unsulating static route
   • Floating static route

6. Configuring static and default routes

   • IPv4
     • Next hop options
       • It can be identified by an IP address, an output interface, or both
         • Next hop path
           • On a next hop static route, only the next hop IP address is specified. The output interface is derived from the next hop.
         • Directly connected static route
           • Configuring a static route directly connected to an outbound interface allows the routing table to resolve this interface in a single search, not two
         • Fully specified static route
           • A fully specified static route has both the output interface and the next hop IP address determined.
       • Checking a static route
         • -show ip route. -show ip route static. -show ip route Red.
     • Setting up a default static route
       • IP route 0.0.0.0 0.0.0.0 ::/24
       • Verification of a predetermined static path
         • show ip route static
           • shows the content of the static paths in the routing table. Observe the asterisk (*) next to the path with the code "S".
     • ip route network-address subnet-mask { ip-addresss | exit-intf }
   • IPv6
     • Static paths for IPv6 are configured with the global configuration ipv6 route command.
       • ipv6 route ipv6-prefix/prefix-length ( ipv6-address | exit-intf )
     • It can be implemented as
       • Standard static path IPv6
       • Default static path IPv6
       • Summary static path IPv6
       • Floating static path IPv
     • Next hop options
       • Next jump IPv6 static path
         • only the IPv6 address of the next jump is specified
       • Static route IPv6 directly connected
         • only the router output interface is specified
       • Completely specified IPv6 static path
         • the IPv6 address of the next jump and the output interface are specified
   • Static floating routes
     • Floating static routes are static routes that have a greater administrative distance than that of another static route or that of dynamic routes.
     • common routing managed distances
       • EIGRP = 90 IGRP = 100 OSPF = 110 IS-IS = 115 RIP = 120
     • Set up a floating IPv4 static path
       • the global configuration command ip route is used and an administrative distance is specified.
       • IPv4 floating static path test
         • traceroute ( ip-address )
     • Configuration of a floating static path IPv6
       • To configure floating IPv6 static paths the global configuration command ipv6 route is used and an administrative distance is specified.
