7.3(3)D1(1)

Description (partial)

Symptom:
+ 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
          0.0.0.0         100.1.1.0       1090519305/0          Down            N/A(3)            Down        Po10                  default <<<<<<<<<<<<<<<<<<<
          10.64.0.89      10.64.0.88      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.

Conditions:
+ Nexus 7000

+ BFD was conifgured wrongly like this:


          sw(config-if)#  port-channel bfd destination 100.1.1.0 <<<<<<<<<<<<<<<<<<<<<< This is a network address and not a host IP address
