How to connect to two ISPs
Hello,
I have 4 dell powerconnect 6248 in a switch stack. Multiple vlans are configured and operating correct. We are connected to internet via ASA
So basically the config is:
Vlan 10 192.168.10 ./24
to
Vlan 30 192.168.30.0/24
Vlan 9 is 192.168.9.0/30
with 192.168.1.1 being the dell's svi & 192.168.1.2 being ASA's inside port
Everything works, inter-vlan, internet etc.
We just got another internet connection.
I have already configured router with basically the same setup
vlan 33 192.168.33.0/30
192.168.33.1 dell svi
192.168.33.2 router inside port
Now I want 1 vlan to use the second router as default gateway
the default gateway current on the switch points to 192.168.1.2 (ASA - First ISP)
I want to use the second ISP for VLAN 20
I have tried just specifying the route manually by
ip route 192.168.20.0 0.0.0.255 192.168.33.2 0.0.0.0 but it doesn't work.
Is it possible to use two ISPs where I have 2 seperate gateways.
Thanks for your time and help.

Hi Gurpreet,
When you say it doesn't work is not able to get any internet access or is it just routing out of the 1st ISP? If you use no ip default route and remove the route to the 1st ISP does it route to the 2nd one? What is the output of show ip route? Does the router have routes back to the vlan configured?

First a slight typo in original post:
Vlan 9 is 192.168.9.0/30
with 192.168.1.1 being the dell's svi & 192.168.1.2 being ASA's inside port
should be 192.168.9.1 being the dell svi & 192.168.9.2 is the ASA's inside port.
Answer to your question:
No by it does not work I meant, it still routing everything over the first ISP
Essentially, what I am trying to say is:
In switch configuration I have
ip route 0.0.0.0 0.0.0.0 192.168.9.2
I've tried various thing but I can't get VLAN 20 to use 192.168.33.2 as a default route instead of 192.168.9.2

The default route has higher priority, try removing the default route and making two static routes with the same metric so that they are treated equally.
