BFD over SVI interface is not working on cisco 7604 Router with Supervisor 32

[Sri v]

I have a Cisco 7604 router running with Suoervisor 32 with the IOS version 15.1.3S6 advance enterprise feature set,

I am unable to configure BFD on my SVI interface.The basic command bfd interval itself not available under SVI interface.

When I gone through the release note, I could see that the particular version will support the same and there is no hardware limitation if BFD supports on it. The same similar IOS version with supervisor 720 its working fine but not with Supervisor 32.

Is there any document says about this ? Is supervisor 32 supports BFD & BFD over svi ? Can anyone answer this pls

Hi,

From link :-

http://www.cisco.com/c/en/us/td/docs/routers/7600/install_config/ES40_config_guide/es40_sw_config/es40_chap4.html#pgfId-1720514

Restrictions for BFD Scale Improvement

The following restrictions apply for BFD scale improvement:

• A BFD session is supported on only RSP 720 and Supervisor 720 (SUP720), it is not supported on SUP32.
• Only BFD version 1 is supported.
• The BFD session can be offloaded only to an ES+ line card interface.
• Ensure that the ES+ Line Card interface configured with the BFD session is on global routing table. Effective from Cisco IOS Release 15.1(3)S and 15.1(2)S1, the interface with a BFD session can be on any Virtual Routing and Forwarding (VRF).
• Each network processor supports a total of 250 sessions distributed across its ports.

Thanks for the Reply alex :)

So it conclude that, Sup32 doesn't support BFD?

but a query from me, I can able to configure BFD on the physical interface.If it is possible on physical interface then it mean that it supports BFD. What abt BFD on SVI interface ?
