- 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?

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;
