We have two 6509 switches as our core network.
These two switches are a hsrp pair, one upstairs, one downstairs.
VTP configured as well, Upstairs switch is the server, downstairs switch is client.
The upstairs switch has a trunk configured to the downstairs 6509.
And a trunk configured to a 7206 router that connects our branches and dr site to the core switches.
OSPF is on the core switches and router.
We recently lost the upstairs 6509 switch.
In order to have the upstairs workstation/server links work while we were trying to get the switch replaced, we had to trunk two 3500 series switches to the downstairs 6509 and router in place of the upstairs 6509.
So, we ended up with:
One 3500 switch ended up as the other core switch, with a trunk to downstairs and a trunk to the router, with an additional trunk to another 3500 for additional ports.
There was no routing protocol on the 3500 series switches and we lost the VTP server.
The Downstairs 6509 was configured with all of the vlans and SVIs with inter vlan routing going on.
With no routing protocol on the 3500 switches (out of the box), what would have been the proper way to configure the 3500s to ensure that all vlans could communicate with the downstairs switch and branches?
The 3500s have servers and workstations. The workstations had to have DHCP addresses from the servers also.
workstations on vlan 10
servers on vlan 20
printers on vlan 30
routers on vlan 40
switch management on vlan 50
I'm really glad you figured out the DHCP mystery! :-)
This was a really good VLAN thread. A lot of basic operational concepts were discussed, so I think you should mark the particular post that actually solved your problem, and Cisco will archive it.
That said, it may be a better idea to start a new thread for the OSPF scenario you want to present to everyone for analysis. This way the thread remains easy to follow along one specific track. Yes?
By the way, thank you kindly for your generous ratings.
As long as the vlan that the router and the 6500 have in common is allowed on all the trunk links then yes they will exchange LSA's.
