BFD between 6500 and Nexus 5K

I'm trying to run BFD for OSPF between 6500E running version 12.2.33 SXH and Nexus 5596UP running Version 6.02. The Nexus 5596 has L3 cards and the correct licence.

 

Here are the config

6500:

_________

!
interface GigabitEthernet7/17
 ip address 30.30.30.1 255.255.255.0
 no ip redirects
 ip ospf network point-to-point
 ip ospf bfd
end

!

router ospf 300
 log-adjacency-changes
 passive-interface default
 no passive-interface GigabitEthernet7/17
 network 30.30.30.0 0.0.0.1 area 0
 network 100.100.100.0 0.0.0.255 area 0
 bfd all-interfaces

 

Nexus 5596:

_________

feature bfd

!

interface Ethernet1/17
  no switchport
  speed 1000
  no ip redirects
  ip address 30.30.30.2/24
  ip ospf network point-to-point
  ip router ospf 300 area 0.0.0.0
  ip ospf bfd

!

router ospf 300
  bfd

!

Now, BFD neighbor is not even showing on the 6500

 

N5596# sh bfd nei

OurAddr         NeighAddr       LD/RD                 RH/RS           Holdown(mu
lt)     State       Int                   Vrf
30.30.30.2      30.30.30.1      1090519042/0          Down            N/A(3)
        Down        Eth1/17               default

 

C6500#sh bfd nei

OurAddr       NeighAddr     LD/RD  RH/RS  Holddown(mult)  State     Int
Cat6500#

 

What did I miss?

 

Thanks for your help

Hi,

When I've used BFD on the Catalyst 6500 with both 12.2SXI and 15.1SY you also need to configure bfd interval milliseconds min_rx milliseconds multiplier interval-multiplier under the interface.

See How to Configure Bidirectional Forwarding Detection for detailed configuration steps.

Is the OSPF peering up and working?

If yes, 12.2.33 SXH is pretty old and I am thinking even though it takes the commands it may not support BFD.

Thanks for your reply. That was the first thing I checked. Cisco feature Navigator confirmed it's supported.
