Hi all,
I have two switches which is interconnected with dot1q trunk and configured management IP with vlan 1
OSPF is configured with management subnet of 2 switches.
My question is will two switches form the OSPF adjancency and neighborship or we have to configure L3 trunk between two switches?

Hi,
an OSPF adjacency should form over any L3 interface with valid IP and matching neighbor settings. Also make sure your IOS does support OSPF.
Given proper config and IOS there should not be any issue.

Rajesh,
As Martin indicated you shouldn't have a problem establishing OSPF adjacency with your existing setup. Two routers sharing the same IP subnet, OSPF enabled on the interface, other parameters like area, stub, hello/hold timers, authentication etc., match they should be able to form neighbor relationship.

Hi,
Thannx for the response.
I have only L2 trunk running between two switches.
With that can we form ospf adjacency provided no configuration issues.

Though you only have a layer 2 trunk between the two switches both switches are configured with an SVI, int Vlan1, and should have network statement under the OSPF process for vlan 1 and they should be able to form neighbor relationship based on that.
