Inter VLAN routing. Cannot ping two VLANS.

[Saji Thomas]

Hello Experts,

I am in a very confused situation where I cannot ping to VLANs on the same layer 3 (6509) switch.

Details: 

There are 4 vlans on the switch: Ex: 

vlan100 (10.129.32.1/22)

vlan 220 (10.222.1.1/24)

vlan 200 (10.140.1.1/24)

and vlan 300 (10.129.50.1/24)

Routing:  eigrp routing for network 10.0.0.0 network.

PROBLEM: All vlans can ping to each other except for vlan 300. Maximum ports are on vlan 100 and some are on other VLANs. Interface 7/1, 7/2 are on vlan 300. Config of 7/1 adn 7/2 is:

switchport mode access

switchport access vlan 300

I do not have any trunk ports as routing is already there. Any ideas and help is very much appreciated.

Regards,

Saji

Hi Ganesh

Thanks,  although I must admit I am unsure of exactly what happens to control plane traffic on an access link between two switches.

Can't help feeling I should know and the answer is obvious :-)

Hi Saji,

Apart from positing show vlan brief and int brief. What is the gateway for all vlan is this 6509 SVI or something else.
