There is no h1 h2 actually. Remove it. Here is the test result after
conversion.

]# ./test_bridge_backup_port.sh

Backup port
-----------
TEST: Forwarding out of swp1 [ OK ]
TEST: No forwarding out of vx0 [ OK ]
TEST: swp1 carrier off [ OK ]
TEST: No forwarding out of swp1 [ OK ]
...
Backup nexthop ID - ping
------------------------
TEST: Ping with backup nexthop ID [ OK ]
TEST: Ping after disabling backup nexthop ID [ OK ]

Backup nexthop ID - torture test
--------------------------------
