CCNA 3.8.b: Network route

Overview:

A network route is used to route traffic to a specific network.

 

Study Notes:

  • A network route is configured to route packets to a specific network
  • You may add many different network routes to the routing table
  • Without a network route, packets will get routed via the default route if one exists
  • Network routes are used for networks that are not locally or directly connected to the router
  • A network route identifies the network, network mask and next hop IP address to send packets to
  • The network mask in a network route can be /1 through /31
  • The network mask in a network route cannot be /0 (default route) or /32 (host route)
  • More specific network routes take precedence over less specific network routes (based on the network mask)
  • Configure an IPv4 network route by typing:
config t
    ip route <network-to-route-to> <subnet-mask> <exit-interface-on-this-router>
    --OR--
    ip route <network-to-route-to> <subnet-mask> <next-hops-ipv4-address>
  • Configure an IPv6 network route by typing:
config t
    ipv6 route <network-to-route-to>/<subnet-mask> <exit-interface-on-this-router>
    --OR--
    ipv6 route <network-to-route-to>/<subnet-mask> <next-hop-ipv6-address>
