New VLAN is unable to route out

jbrunson1001 · ‎10-23-2015

We have a main data vlan routing out successfully

router int Gi0/1.208 to switch int Gi0/27 and interface vlan208

I have created a new vlan that does not route out successfully

router int Gi0/1.105 to switch int Gi0/27 and interface vlan105

Gi0/27 is configured as a switchport mode trunk.

When I connect to a port on the switch configured as switchport access vlan 208, I get an ipaddress and am able to access the network successfully.

When I connect to a port on the switch configured as switchport access vlan 105, I get an ipaddress, but am NOT able to access the network. I can ping the switch and ping the router. But I am not able to ping anything further than the router.

What am I missing in my router configuration?

What is beyond the router ?

Whatever it is it sounds like it does not have a route back to the new IP subnet.

If it is internet then you may need to add routes to the upstream device and maybe also NAT rules.

Can you supply more details.

"Please check routing table, as you are able to reach to router and further router not; then check the routing."

"Whatever it is it sounds like it does not have a route back to the new IP subnet."

This ended up being the main issue.

After creating new subnets at the remote office, routes were configured to corporate, but we had to add static routes from the corporate router back to the remote office to recognize them.

Thanks for pointing me in the right direction.

Can you provide us with some interface configurations for your router and switch?

Hi,

What is the routing table and is any NAT rule configured on Router for lan 208.

what difference are you seeing in router configuration for both the VLANs ?
