Hi,

Are you using Cisco devices?
Here are some factors to condisder in troubleshooting:

If your using cisco.
1. try to check the configuration of the subinterfaces on your router, you said that you’ve added additional router with different vlan ID, maybe you haven’t included that into your subinterfaces.

2. On your added router, try to configure a default route onto outgoing network, maybe the packets from the inside network can’t go outside because of routing. As you can see, If your using a switch in vlans, they are in the same network, if not, they are in differnt vlans but ip address is not a factor for a switch. In a router, 1 port/interface equals 1 network.

For me, it is not advisable to add a router down to your vlan network but its ok if you know how to use your devices.

    Yup i'm using cisco divice, I add this new router to cater my additional VLANs and I notice that cisco 1841 router can cater only six VLANs sub interface. Each router has its own sub interface with static ip address belong to its VLAN and they are connected in the same switch hub and both router eth0/0 has the same ip segment but the error still, do I need to activate some cisco features like router rip etc.. Thanks; BSM1220

    I dont believe your statement about the subinterfaces on an 1841 to be accurate. Router(config-if)#int fa0/0.1 Router(config-subif)# %LINK-5-CHANGED: Interface FastEthernet0/0.1, changed state to up Router(config-subif)#int fa0/0.2 Router(config-subif)# %LINK-5-CHANGED: Interface FastEthernet0/0.2, changed state to up Router(config-subif)#int fa0/0.3 Router(config-subif)# %LINK-5-CHANGED: Interface FastEthernet0/0.3, changed state to up Router(config-subif)#int fa0/0.4 Router(config-subif)# %LINK-5-CHANGED: Interface FastEthernet0/0.4, changed state to up Router(config-subif)#int fa0/0.5 Router(config-subif)# %LINK-5-CHANGED: Interface FastEthernet0/0.5, changed state to up Router(config-subif)#int fa0/0.6 Router(config-subif)# %LINK-5-CHANGED: Interface FastEthernet0/0.6, changed state to up Router(config-subif)#int fa0/0.7 Router(config-subif)# %LINK-5-CHANGED: Interface FastEthernet0/0.7, changed state to up Router(config-subif)#int fa0/0.8 Router(config-subif)# %LINK-5-CHANGED: Interface FastEthernet0/0.8, changed state to up Router(config-subif)#int fa0/0.9 Router(config-subif)# %LINK-5-CHANGED: Interface FastEthernet0/0.9, changed state to up Router(config-subif)#int fa0/0.10 Router(config-subif)# %LINK-5-CHANGED: Interface FastEthernet0/0.10, changed state to up - thats running the following IOS version: Router#sh ver Cisco IOS Software, 1841 Software (C1841-ADVIPSERVICESK9-M), Version 12.4(15)T1 Might need to update your IOS... Additionally, in the config you've described, what is the default gateway of the hosts / switch? and do you have all VLANS being trunked to just one router?
