+ * ospf_vty.c: forece default route LSA to be re_issued whenever
+ cost is changed ( [no] ip ospf area XXX default-cost YYY)
+ Support ignore-mtu option
+ * ospfd.h: define OSPF_MTU_IGNORE_DEFAULT
+ * ospf_packet.c: support ignore-mtu option
+ * ospf_interface.h: field added for skipping MTU check
+ * ospf_interface.c: fix memory leak in ospf_crypt_key_delete()
+ Set mtu_ignore field to default value
+ * ospf_abr.[ch]: export ospf_abr_announce_network_to_area()
+ * ospf_ism.h: add MACRO to convert internal ISM status into SNMP
+ correct values
+ * ospf_snmp.c: add sanity check on LSA type in lsdb_lookup_next()
+ convert OSPFIFSTATE internal status into SNMP values
+
2005-09-28 Alain Ritoux <alain.ritoux@6wind.com>
* ospf_packet.c: use new md5 API
