* ospf6_spf.c: ditto.
* ospf6_top.c: ditto.
2004-10-06 Yasuhiro Ohara <yasu@sfc.wide.ad.jp>
* ospf6_snmp.c: add partial support for SNMP
(i.e. ospfv3AreaLsdbTable).
* OSPFv3-MIB.txt: Net-SNMP translate Unsigned32 range
(0..'FFFFFFFF'h) incorrectly to (0..-1). Those parts for
Unsigned32 range are changed to (0..4294967295).
Also, doubtful 'not-accessible's are changed to read-only.
2004-10-06 Yasuhiro Ohara <yasu@sfc.wide.ad.jp>
* ospf6_snmp.[ch], OSPFV3-MIB.txt: start supporting SNMP.
