G+_Eddie Foy Posted June 16, 2015 Share Posted June 16, 2015 For you Cisco boys out there: Having trouble wrapping my head around InterVLAN routing. Cisco 3750 48 port Layer 3 Cisco 2960 24 port Layer 2.5? ( not full layer 3 from what I've gathered but after a 'SDM preferred lanbased-routing' command I get the 'ip route' commands) Main goal is internet access for VLAN 10, but seperation from main LAN Win7 can ping Linux machines. So the VALN is working as is the trunking between switches. All I've tried thus far, I can't ping the router (192.168.1.1) (And yes, the NAS/Server has 4 ports. 1 on LAN and 1 on VLAN and ping-able by both. 2 unused) (and to avoid the TL;DR trying to explain the network layout, here's a pic) Link to comment Share on other sites More sharing options...
G+_V.T. Eric Layton Posted June 16, 2015 Share Posted June 16, 2015 My Cisco cert will be expiring this coming February. It never earned me a penny. Only managed to get one job interview from having it. They hired the 19 year old kid part-time for $9.50/hr. I guess they didn't think the old gripper with 20+ years in the electronics/computer field would work for that low of a wage. I wish they would have at least asked me, though. $9.50/hr beats the hell out of $0.00/hr. Ooops... Sorry. < /rant> Link to comment Share on other sites More sharing options...
G+_Eddie Foy Posted June 16, 2015 Author Share Posted June 16, 2015 V.T. Eric Layton feel free to rant on my posts! I like rants! I wouldn't look to be a cisco guy, but as an addition to the quill. @$9.50, where you at???? Seen Burger King offering $10hr, nearly a decade ago. I'd consult before I took $10. (well basically consulting now, but for CNC laser service) Link to comment Share on other sites More sharing options...
G+_V.T. Eric Layton Posted June 16, 2015 Share Posted June 16, 2015 Eddie Foy I'm in Florida, where middle-aged folks are put out to pasture early. Burger King and other places like that only hire the scared teen types that they can abuse and bully. Link to comment Share on other sites More sharing options...
G+_Travis Hershberger Posted June 17, 2015 Share Posted June 17, 2015 My first guess is that you'll need to add a route between the 2nd vlan and the internet. Sounds like one is already setup for communications between the vlans. Link to comment Share on other sites More sharing options...
G+_Enoch Conley Posted June 17, 2015 Share Posted June 17, 2015 What's the default gateway on the 3750? Link to comment Share on other sites More sharing options...
G+_Eddie Foy Posted June 17, 2015 Author Share Posted June 17, 2015 Travis Hershberger coms between vlan aren't there (coms between swicthes is, ie:trunk lines) here's the routing tables 3750: ip default-gateway 192.168.1.1 ip classless ip route 0.0.0.0 0.0.0.0 192.168.1.1 ip route 192.168.10.0 255.255.255.0 192.168.1.1 and the 2960: ip default-gateway 192.168.1.1 ip route 0.0.0.0 0.0.0.0 192.168.1.1 ip route 192.168.10.0 255.255.255.0 192.168.1.1 ip route 192.168.10.156 255.255.255.254 192.168.1.1 I've even tried a single IP: ip route 192.168.10.159 255.255.255.254 192.168.1.1 feeling like the dest IP and mask with all 0's might be the culprit. I've also used the " switchport nonegotiate " to avoid VLAN hopping. Link to comment Share on other sites More sharing options...
G+_Travis Hershberger Posted June 17, 2015 Share Posted June 17, 2015 I have a feeling your right about that route. Try changing it to the ip and subnet that needs internet access. Shouldn't that read "ip route 192.168.10.0 255.255.255.0 192.168.1.1"? One of these days I'll break down and install the Cisco virtual lab software so I can actually try this stuff virtually.

G+_Eddie Foy Posted June 17, 2015 Author Share Posted June 17, 2015 Travis Hershberger that route is on both switches. (third route on each) That's where I started. Then drilled it down to single IPs Link to comment Share on other sites More sharing options...
