Hope someone can shed some light here. I have a little network drama which I'm trying to get resolve as soon as possible. To give you a little background;
We have CISCO SG300 small business switches configured in layer 3 We have a CISCO 1921 managed router on site (Managed by the provider) Windows 2012 running DNS/DHCP/AD etc...
Currently our network is configured to have 3 VLANS.
VLAN1 (default data) 10.1.0.xxx/24
VLAN110(VOIP) 10.1.1.xxx/24
VLAN111(Wireless) 10.1.2.xxx/24
Issue is I'm starting to run out of IP address for VLAN1 data range. So I have added another VLAN2 10.1.3.xxx/24 on the router and trying to configure windows 2012 DHCP to have superscope including 10.1.0.xxx & 10.1.3.xxx ranges together to server for data.
However, for some reason I can't seem to get new VLAN2 talking properly. What I have done so far on the switches;
Main switch which is connecting to cisco 1921 managed router, I have tagged the port to VLAN2. Also added VLAN2 and configured IP interface for VLAN2 as 10.1.3.8 on the switch and 10.1.3.253 as gateway. I have all other VLAN1/110/111 ip interfaces configured 10.1.0.8/10.1.1.8/10.1.2.8 respectively.
Here are the settings on the switch for IPv4 interface and routes
From the switch:
Source IP 10.1.0.8 (VLAN1) pinging 10.1.3.8 (VLAN2) – success 100%
Source IP 10.1.0.8 (VLAN1) pinging 10.1.3.7 (VLAN 2 on 2nd switch) – success 100%
Source IP 10.1.0.8 (VLAN1) pinging 10.1.3.251 (VLAN2 current DG on the router) - success 100%
Source IP 10.1.3.8 (VLAN2) pinging 10.1.0.8 (VLAN1) – success 100%
Source IP 10.1.3.8 (VLAN2) pinging 10.1.0.7 (VLAN1 on SWITCH 07) – failed
Source IP 10.1.3.8 (VLAN2) pinging 10.1.0.253 (VLAN1 default gateway on the router) – failed
It seems traffic from 10.1.3 subnet doesn’t know how to get to 10.1.0 subnet on the switch? I may be missing a route?
Any help would be appreciated. Thank you.
