Description (partial)

+ Issue is that this entry is not being able to be removed and no new BFD session can be configured on PO 10:

          sw# show bfd neighbors

          OurAddr         NeighAddr       LD/RD                 RH/RS           Holdown(mult)     State       Int                   Vrf
       1090519305/0          Down            N/A(3)            Down        Po10                  default <<<<<<<<<<<<<<<<<<<
      1090519048/0          Down            N/A(3)            Down        Po20.1                default

+ We attempted to reconfigure but we were unable to remove this entry.

+ Tried on another port channel as well but we are still unable to remove this entry.

+ Nexus 7000

+ BFD was conifgured wrongly like this:

          sw(config-if)#  port-channel bfd destination <<<<<<<<<<<<<<<<<<<<<< This is a network address and not a host IP address
