Can 2960 share a single Internet gw without additional routers?

hello! first, excuse my super noobness! in my research i think this capability is beyond this switch. this is a "limited l3" switch. i just wanted to verify this with you pros. i'm running this on my home lab. single wan drop shared by everything at home. it is the typical 192.168.1.1. can i share that gw with vlan2, 3? vlan1 is on 192.168.1.x subnet.

 

ip routing is already enabled

Yes.  What problem are you having and what router are you using? 

Also what are you trying to do?

 

You could route l3 to the next hop at 192.168.1.1.

You could configure 802.1q trunk -- but then your router needs to have sub-interfaces -- if your router can be configured, with just a 2960 @ layer 2.

 

hi, my topology is one linksys e2000 then one 2960tl-l running ios15se7 and that is all. 

on the 2960 i left vlan1 on 192.168.1.0/24 default, vlan2 is 10.0.0.0, vlan3 is 10.0.1.0, vlan4 is 10.0.2.0.

i want vlan 2-4 to be able to access the internet without any additional l3 routers in the topology. from my research this is not possible with 2960 only 3xxx series and true l3 switches w/full routing capabilities.

 

sorry i was not very clear in the initial question.

You can create different L2 vlan in your 2960 switch and then create corresponding L3 interface in the same switch. From the L3 switch you can create a default route pointing to internet gateway.

i did not see any additional routing capabiliies in the manual. my vlan 2,3,4 are already created but no routing to gw.

 

to be more specific:

vlan2=10.0.0.0/24

vlan3=10.0.1.0/24

vlan4=10.0.2.0/24

 

all the vlan can ping one another, but vlans2 through 4 can't ping vlan1 (192.168.1.0/24) somehow.
