I have a Cisco router and a 6509E switch. I do not have access to the router but do have access to the switch. The vendor tells me that on the switch he has setup primary IP and secondary IPs on his interface. On my switch I am doing dot1q VLANS. At this point the only VLAN that can pass traffic to their router is the default VLAN. Any of the other VLANs will not pass any traffic to the router. I am at a loss as to what I am missing. InterVLAN routing on my network is working fine but I cannot see any of the gateway addresses i.e.: secondary IPs on their router. Any help will be greatly appreciated!
