You are looking at a small network with a HQ and Branch router. At the HQ there is a webserver located and many users from the branch office are accessing this webserver. Between HQ and Branch there are two links. A fast cheap FastEthernet connection and a slow and very expensive serial link. You want to make sure the serial link will only be used when the FastEthernet fails. You don’t trust the layer 1 and 2 information of the interface so you want to make sure you use layer 3 information to check if the webserver is reachable.
- All IPv4 addresses have been preconfigured for you.
- Configure router Branch with a static route to reach the webserver through the FastEthernet link.
- Configure router Branch with another static route to reach the webserver through the serial link. Make sure this static route is only used when the FastEthernet static route disapears.
- Configure IP SLA on router Branch to ping the IP address of the webserver. Once it starts it should never stop.
- If you don’t receive a ping for 5 seconds from the webserver router Branch should remove the static route for the FastEthernet link from the routing table.
- If everything goes ok all traffic will now be sent through the serial link.
