By "what protocol to use" I assume you mean which routing protocol. Cox probably won't run a routing protocol with you.
You will need to configure the ethernet interface that you have going towards the cable modem as a DHCP client. Use the interface configuration command "ip address dhcp" for this. In my experience with Cox, I couldn't get the network to assign an address until I assigned the name of the computer that had been connected to the cable modem to the router. If you previously had a computer on this connection, use the command "ip address dhcp hostname (hostname)" instead of the command above.
As for the default gateway, Cox will send that along with the address assignment, but I have looked through Cisco's documentation for a while and I have not found anything about this default gateway being added to the routing table. After setting this up, you can check the routing table of the router by entering the command "show ip route" and see if the Cox-assigned default gateway is the default route in the table.
Also, if you currently have a computer on this cable modem, have it release it's IP address, power down the cable modem, connect the router to the cable modem, and power up the cable modem. After this, your router should receive an address from the network.
We have 3 identical switches configured by someone else and would like to claim some of the Gigabit ports(G1/G2/G3/G4) for use on servers. When we try to change the wiring and configuration, we run in to connectivity issues. Attached is a des...
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
