Zebra uses raw IP socket (fd 4 below) to send multicasts through
multiple interfaces, so it's not a surprise:

$ fstat -p 125
USER     CMD          PID   FD MOUNT      INUM MODE         SZ|DV R/W
root     ospfd        125 root /             2 drwxr-xr-x    1024  r
root     ospfd        125   wd /             2 drwxr-xr-x    1024  r
root     ospfd        125 text /usr      24539 -r-xr-xr-x  426628  r
root     ospfd        125    1 /          1126 crw-rw-rw-    null rw
root     ospfd        125    2 /          1126 crw-rw-rw-    null rw
root     ospfd        125    3 /          1126 crw-rw-rw-    null rw
root     ospfd        125    4* internet stream tcp d20ade00
root     ospfd        125    5* internet raw ip d2905ec0
root     ospfd        125    6* local stream d2f98dc0
