Server Client
2001:1::803/64 <-> 2001:1::805/64
2001:2::804/64 <-> 2001:2::806/64
Server side fib binary tree looks like this:
(2001:/64)
/
/
ffff88002103c380
/ \
(2) / \
(2001::803/128) ffff880037ac07c0
/ \
/ \ (3)
ffff880037ac0640 (2001::806/128)
/ \
(1) / \
(2001::804/128) (2001::805/128)
Delete 2001::804/64 won't cause prefix route deleted as well as rt in (3)
destinate to 2001::806 with source address as 2001::804/64. That's because
2001::803/64 is still alive, which make onlink=1 in ipv6_del_addr, this is
where the substantial difference between same prefix configuration and
different prefix configuration :) So packet are still transmitted out to
2001::806 with source address as 2001::804/64.
So bump genid will clear rt in (3), and up layer protocol will eventually
find the right one for themselves.
This problem arised from the discussion in here:
