1  . set interface ip address

host-eth1 (up):
10.0.1.2/24
host-eth2 (up):
10.0.2.2/24

2  . del one

set interface ip addr del host-eth1 10.0.1.2/24

host-eth1 (up):
host-eth2 (up):
10.0.2.2/24

 3. add route

10.0.0.0/8

4.  test

10.1.1.1—will lookup OK .

10.0.1.1—will lookup fail .

when delete leaf in function "unset_leaf", need modify like this:

old:

old_ply->dst_address_bits_of_leaves[i] =
clib_max (old_ply->dst_address_bits_base,
a->cover_address_length);

new:

old_ply->dst_address_bits_of_leaves[i] = a->cover_address_length;
