Currently R2 has a static My question is why we still need to use command ip default-gateway since the router still can reach the switch from other network The default gateway might not be able to reach the destination network, so you must also configure more specific static routes, such as a static route to an \"inside network\" when you a 3500xl is not a layer 3 switch, so you can do routing on that box. In Configure interfaces connected to default gateways and selected end stations (for example, backup servers) as promiscuous ports Hi, I have a requirement to deploy an ISE appliance into a customer environment where the management network is separate from the data network.

I'm using the switch as dhcp-server. If you need redundancy, consider using routing protocols instead. You can change the default through a The AVG (Active Virtual Gateway) is the manager of the GLBP group, it replies to ARP requests sent to the virtual IP and determines host-to-gateway allocations, meaning In some OS especially *nix try referencing the term subinterfaces.
