2 Gateways/Default routes

Unanswered Question
May 26th, 2008

Hi All,

Is it possible to configure 2 gateways or 2 default routes on a switch.

The setup is we have an old 4000 series switch and a new 3560 switch.The new switch is connected to an MPLS cloud which is for datacenter access and does not have internet access. so when i move the users into the new switch, how do we point users to go to old switch gateway for internet access and new switch gateway for datacenter access..


I have this problem too.

You do not indicate in your post whether the 3560 will be operating as a layer 2 switch or operating as a layer 3 switch. It would be important to know this to be able to accurately answer your question.

Thanks for the quick reply..The 3560 switch is operating as L3.Ip routing is enabled.ip classless/ip subnet-zero etc enabled. We also have VLAN's configured in the 3560.

If the 3560 is operating as a layer 3 switch with ip routing enabled then you do not need 2 gateways or 2 default routes. You would just need for the 3560 to have a route for the data center through the MPLS and to have a default route pointed back through the old 4000 switch.

As of now we have one default route pointing to the MPLS. So i guess we will have to remove that and add allllll... the different networks using static route that will be in MPLS cloud right.

No routing protocols planned. only static routes. i guess i can have static routes for all the private networks ranges and one default route pointing to the old switch default gateway(firewall/router).
