3550 is running ospf...originally the 6500 is just using layer 2 wherein it is using the vlan 20 ip range.
actually i dont have any access on the 3550 yet..the vlan 30 i specified is just an assumption anyway..one thing for sure the vlan IDs on this links are different..coz am getting vlan mismatch on the interface coonected..
please bear with me as i wanted to sort out this prob asap..
Do you mean it does not do routing between vlan 10 and 20? Or just that it is not running ospf?
In any case for this to work the 6500 will have to route between vlan 10 and 20 (or you need a trunk to the 3550 so the 3550 can route between all the vlans) and the 3550 will have to know a route to vlan 10. It can learn this via ospf (if the 6500 talks ospf) or it will need to have a static route to vlan10.
taking for granted they havent established neighboship , i should be able to reach at least the interface on the far switch where my core is connected, from any of my vlans coz i have intervlan routing and that is part of a subnet of 1 of my vlan..
if you ping the vlan30 interface from vlan 10, your intervlan routing will forward the echo-request packets to the 3550 and it should respond by sending echo-reply packets back to the source (the host you ping from).
The problem is that the source is a vlan10 address so the 3550 does not know where to send these reply packets to (and probably drops them, or sends them to internet)... hence your ping does not work.
