[c-nsp] Unable to create BFD session on C6500

[Мурат Каипов]

Hello Marco.
Can you provide what type of Line Cards you use and check your Cat6500 for
this restrictions:

   -  Cisco Catalyst 6500 series switches support up to 100 BFD sessions
   with a minimum hello interval of 50 ms and a multiplier of 3. The
   multiplier specifies the minimum number of consecutive packets that can be
   missed before a session is declared down.
   -  If SSO is enabled on a dual RP system, the following limitations
   apply:
      -  The maximum number of BFD sessions supported is 50.
      -  The minimum hello interval is 500 ms with a multiplier of 3 or
      higher.
      -  If EIGRP is enabled, the maximum number of BFD sessions supported
      is reduced to 30.
      -  Echo mode is supported on Distributed Forwarding Cards (DFCs) only.
   -  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.
   -  To enable echo mode the system must be configured with the no ip
   redirects command.
   -  During the In Service Software Upgrade (ISSU) cycle the line cards
   are reset, causing a routing flap in the BFD session.
