Route to the 2nd ISP

Hi,

if what you want to achieve is some type of traffic uses ISP1 and other uses ISP2 then you'll have to use PBR:

http://www.cisco.com/en/US/docs/switches/lan/catalyst3750/software/release/12.2_55_se/configuration/guide/swiprout.html#wp1228588

Now you can use either a SVI or a routed port for connecting to ISPs.

Regards.

Hi,

of course Paolo's answer reminded me that indeed this is a switch that doesn't support NAT( the only one I know that supports it is the 6500 serie) so you'll need a router indeed to go on the internet.

That doesn't work good or doesn;t work at all with switches.

You need to use a router for that.

Re: Route to the 2nd ISP

Im using L3 switch.

What I'd like to do, is

if I use example Vlan 30

route traffic for Vlan 30 to a specific port that is configured to default Gateway of 10.0.0.137 which is my secondary ISP

You might be able to implment VACL's and route traffic to a specific port within a certain VLAN.

Re: Route to the 2nd ISP

here is the scenario to make it clear. I want PC1 to access the ISP 2 on the specific port Fa0/2.

then again, all pc's the default gateway is ISP1.

Would you think ACL is the bestway to answer my question?

Hi,

this won't work because the switch can't do NAT.
