Implement and Troubleshoot Static Routing
Static routing – administratively configured route
Admin distance of 1
Static routes with AD of 255 are never entered into the routing table
Show ip route static
Ip route [network] [subnet] [next hopIP or Interface] <options: admin distance, track, tag>
If route is pointed to a broadcast interface, it’ll only be in the routing table when the interface is up
- Router will ARP for each destination
- Prevent the ARP by defining a next hop address
-
Ip route [network] [subnet] <next-hop-address> <interface>
-
Floating static route
- Change the AD of the static route
- This route gets used when a route with a better AD for the network is removed from the routing table
- Backup route
- Can also be done with creating a less specific route
