aix刪除永久默認路由

查看當前的默認網關

1.netstat -rn
會看到有多條的default.
如果用route命令（或smitty route)去刪除，下次重啓後，又會回來；所以要從ODM裏刪除。
2.查看ODM信息
# lsattr -El inet0
authm 65536 Authentication Methods True
bootup_option no Use BSD-style Network Configuration True
gateway Gateway True
hostname appserv1 Host Name True
rout6 IPv6 Route True
route net,-hopcount,0,,0,192.111.10.251 Route True
route net,-hopcount,0,,0,192.110.9.63 Route True
route net,-hopcount,0,,0,192.111.11.251 Route True
route net,-hopcount,0,,0,192.110.9.251 Route True
# odmget -q "name=inet0" CuAt
CuAt:
name = "inet0"
attribute = "hostname"
value = "host1"
type = "R"
generic = "DU"
rep = "s"
nls_index = 24
CuAt:
name = "inet0"
attribute = "route"
value = "net,-hopcount,0,,0,192.111.11.251"
type = "R"
generic = "DU"
rep = "s"
nls_index = 0
CuAt:
name = "inet0"
attribute = "route"
value = "net,-hopcount,0,,0,192.111.10.251"
type = "R"
generic = "DU"
rep = "s"
nls_index = 0
CuAt:
name = "inet0"
attribute = "route"
value = "net,-hopcount,0,,0,192.110.9.251"
type = "R"
generic = "DU"
rep = "s"
nls_index = 0
CuAt:
name = "inet0"
attribute = "route"
value = "net,-hopcount,0,,0,192.110.9.63"
type = "R"
generic = "DU"
rep = "s"
nls_index = 0
其中正確的應是192.110.9.63，其它都是多餘的。
3.逐條刪除沒用的默認路由
# chdev -l inet0 -a delroute="net,-hopcount,0,,0,192.111.11.251"
Method error (/usr/lib/methods/chginet):
0514-068 Cause not known.
0821-279 writing to routing socket: The process does not exist.
0821-103 : The command /usr/sbin/route delete -net -hopcount 0 0 192.111.11.251 failed.
###刪除其它(略)###
出現上面的報錯信息，應該是AIX5.3的“誤報”（至少在5300-08-01上是這樣，AIX6不會）可以不用理會。
4.確認生效
# lsattr -El inet0
authm 65536 Authentication Methods True
bootup_option no Use BSD-style Network Configuration True
gateway Gateway True
hostname appserv1 Host Name True
rout6 IPv6 Route True
route net,-hopcount,0,,0,192.110.9.63 Route True
# odmget -q "name=inet0" CuAt
CuAt:
name = "inet0"
attribute = "hostname"
value = "appserv1"
type = "R"
generic = "DU"
rep = "s"
nls_index = 24
CuAt:
name = "inet0"
attribute = "route"
value = "net,-hopcount,0,,0,192.110.9.63"
type = "R"
generic = "DU"
rep = "s"
nls_index = 0
