In this case, why is the 'ip default-gateway' command necessary on the switch? The host has been configured with the default gateway's IP address and will use ARP to find the default gateway's MAC address. The switch should know which port the router is connected to because of the MAC address table that it builds. So, the host sends the traffic containing the default gateway MAC address to the ...
The terms "default gateway" and "gateway of last resort" are often used interchangeably, but there's a subtle difference in their usage. A default gateway is the IP address of a router that a device uses to reach networks outside its own subnet.
A Gateway of Last Resort or Default gateway is a route used by the router when no other known route exists to transmit the IP packet. Then What if I do not set default gateway and what if I set? What makes the difference and What is recommended? Can anyone explain me with example?
The reason, that there can't be more than 1 default-gateway is not, that the default-ggateway is configured in global configuration mode, but because a second "defaault-gateway" statement will override an already existing "default-gateway" statement.
Would like to know under which scenarios we would ip default gateway command on a switch instead of ip route 0.0.0.0 0.0.0.0I know that default gateway (is usuallly a router interface) and is something that you configure when you need to reach a network outside of your current network. But let us assume that we have a PC and a switch and a Router how should the default gateway's be set? and what is the logic behind setting it this way.
