Can not ping router within vlans

I have a 2610 with NM-4E which is configured as such; E1/0 10.1.10.1, E1/1 10.1.20.1, E1/2 10.1.30.1, E1/3 10.1.30.1

I have my 5505 setup as Vlan510 5/1-8, Vlan520 5/9-16, Vlan530 5/17-24

E1/1 connected to 5/1, E1/2 connected to 5/9, and E1/3 connected to 5/17.

The router and switch configuration verify that everything is as it should be yet when I configure my laptop with 10.1.30.15 and connected it to 5/2 it can not ping 10.1.30.1. I check the router and the show arp see the 10.1.30.15. I check the switch and it show a device conected on 5/2 which wuld be my laptop.

Does anyone know why I can not ping the route ? by the why the same thing happens if I change the laptops ip addres to reflect the correct subnet and plug into the switch at 5/10 or 5/18 respectively.

Thanks,

Steve

Re: Can not ping router within vlans

You said: 5505 setup as Vlan510 5/1-8, Vlan520 5/9-16, Vlan530 5/17-24

E1/1 connected to 5/1, E1/2 connected to 5/9, and E1/3 connected to 5/17.

That would mean E1/1 10.1.20.1 would be vlan 510.

E1/2 10.1.30.1 would be in vlan 520.

E1/3 10.1.30.1 would be in vlan 530.

How are you able to put in the same ip address on two different interfaces on the same router?? e1/2 and e1/3.

Another thing would be you said you are connecting a PC in 5/2 which according to you is in vlan 510. Yet the ip address belongs to 10.1.30.0 network which would mean it should be in vlan 530. so, clearly it's misconfigured if all the info provided is accurate. However, I am most curious to know how the rotuer allow you to configure 2 different interface in teh same router to have the same ip address.

Thanks for catching that, the interfaces are actually; E1/1 10.1.20.1, E1.2 10.1.30.1, E1/3 10.1.40.1

Re: Can not ping router within vlans

Still will not going to work since it's not configured correctly because per your information 1/2 is connected to 5/9 of the switch and you said - Vlan520 5/9-16. So that means 10.1.30.1 is in vlan 520. do you see that? and then you said "when I configure my laptop with 10.1.30.15 and connected it to 5/2" - well, 5/2 is in what vlan? According to you it's in -> Vlan510 5/1-8. So, you have a PC in subnet 10.1.30.x with ip address of 10.1.30.15 but the port is in vlan 510. Therefore, you will not be able to ping ip address 10.1.30.1 in vlan 520.
