I can't get BFD to work - it seems no matter where I try it, what I try it on, it just never works. 
It seems so easy in the DOCs ...
I'm trying to get it working on four 3560X's running Version 15.2(1)E2 which according to the release notes ( http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3750x_3560x/software/release/15-2_1_e/release/notes/OL29707.html#95096 ) it should work.
- (IP Base) Support for Bidirectional Forwarding Detection, which is a detection protocol designed to provide fast forwarding path failure detection times for all media types, encapsulations, topologies, and routing protocols.

I have two of the same switch, code, license connected together via Gi0/1. Configs are virtually the same, except IP on Sw2 is .2:
interface GigabitEthernet0/1
bfd interval 200 min_rx 250 multiplier 3
end
Switch1#sh run | s ospf
router ospf 65521
router-id 1.1.1.1
passive-interface default
no passive-interface Vlan1
no passive-interface GigabitEthernet0/1
network 10.0.0.0 0.255.255.255 area 0
network 169.254.0.0 0.0.255.255 area 0
bfd all-interfaces
Switch1#
Switch1#sh run int vlan 1
Building configuration...
Current configuration : 59 bytes
!
interface Vlan1
ip address 169.254.0.1 255.255.0.0
end
But when I do sh BFD !anything - I get nothing.
I have debugs for bfd:
Switch1#sh debug
BFD:
BFD event debugging is on
BFD packet debugging is on
Switch1#
But no output.
If I shutdown the interface on one, nothing happens with BFD.
No BFD neighbors.
Any help would be appreciated.
Thanks!
