Hi,

We have found an issue in OSPF6d where the LSAs are not removed from the database even after receiving Maxage LSupdate from the peer(external route withdraw or IPv6 address remove), as the maxage remover is not called and the lsa_expire thread is set to null and the lsdb hook_remove is called.
Even after 5-6 minutes of receiving the LSupdate from peer the intra-prefix LSA (PL 3200::/64) and AS-ext LSA (PL 33:33:33::/64) is still @ maxage.
