multiple ip's on vlan interface?

we have a router/switch(all in one) cisco 6500

the vlan 230 interface look like this:

interface Vlan230 description Wi-Fi_VLAN ip address 192.168.230.254 255.255.255.0 secondary ip address 10.101.230.254 255.255.255.0 ip helper-address 10.100.100.103 ip helper-address 10.100.100.104 no ip redirects no ip unreachables no ip proxy-arp

the problem is that if i connect my laptop to one of the ports(access to vlan 230 of course) with ip address: 192.168.230.11 (for example), with default gateway: 192.168.230.254 , i cannot establish a connection to outside networks.

for example: c:\\> tracert 212.150.240.240

1 ...... 10.101.230.254 2 * * * * 3 * * * * and so on...

in other words - the route goes to the 10.101.230.254 instead of

192.168.230.254

why is that and how i can solve it?

thanks alot. aorry about my bad english ;)

Are there any other siwtches or routers between the 6500 and the IP address 212.150.240.240

Is the route 192.168.230.0/24 (VLAN 230 secondary) being advertised to its neighbours ?

Post the routing process config form the 6500 and the output of sh ip route

  1. there is several routers between the 6500 and the ip-address
212.150.241.240
  1. the route for network 192.168.230.0/24 are advertised to the other routers of our LAN
  2. Msfc-Comp is the 6500 router that my laptop are connected to

#sh ip route ... C 192.168.230.0/24 is directly connected, Vlan230

Migdal-Msfc is another 6500 on our LAN >

Migdal-Msfc#sh ip route ... D EX 192.168.230.0/24 [170/3072] via 10.100.254.253, 7w0d, Vlan1

But i dont think that the problem is with the routing process between the routers, because as i said, my laptop connected directly to Msfc-Comp (on layer 2) - the router with the vlan 230 interface, and although the dafult-gateway is 192.168.230.254 (the secondary ip-address on vlan 230 interface) , the routing outside goes to

10.101.230.254 (the primary ip-address on vlan 230 interface) - like you can see on the pic:

thanks alot.

Traceroute shows you the IP address of the device along the path to the destination. So seeing 10.101.230.254 as the first hop is correct.

Traceroute work by increment the TTL field. Each router checks the TTL value before it reroutes a packet that it has received and if the TTL has expired it generates an ICMP packet. That ICMP time-exceeded packet will use the PRIMRY IP address of the router's interface.

The second router along the path probably does not know about tthe IP subnet 192.168.230..0/24

closing the CP VPN client (although it was not connected !) - solves the problem! :-)

thanks!
