Re: BFD over OSPF & NSF/SSO Catalyst 6500

Hi Radio,

Debug output you say does not display anything.. it is curious

Relating the 6748 and BFD support, if you look at this url:

http://www.cisco.com/en/US/docs/ios/iproute_bfd/configuration/guide/irb_bfd_ps6441_TSD_Products_Configuration_Guide_Chapter.html
,you can see:

"Cisco IOS Release 12.2(33)SXI2 and Cisco Catalyst 6500 Series Switches
BFD SSO is supported on Cisco Catalyst 6500 series switches using the
E-chassis and 67xx line cards only. Centralized Forwarding Cards (CFCs) are
not supported. "
I have E-chassis, but I have WS-X6748-GE-TX + WS-F6700-CFC, this is, i am
using CFC... i am not sure if the above note is only a restriction for SSO
(and the BFD session must go up, but without the SSO funcionality), or if
this note means that you can run BFD using 6748+CFC...

Anyone knows about this restriction?

Best Regards
