aix删除永久默认路由的方法

发布时间:2017-03-21 16:02

ifconfig 添加的ip地址有可能会丢失,实验时后如果Aping不通B请依次pingR1 R2 R3的各个端口,查询问题所在。
要想实现aix删除永久默认路由,首先要查看当前的默认网关:
1. netstat -rn
会看到有多条的default.
如果用route命令(或smitty route)去删除,下次重启后,又会回来;所以要从ODM里删除。
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
其中正确的应是192.110.9.63,其它都是多余的。

3.逐条删除没用的默认路由
# 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.
###删除其它(略)###
出现上面的报错信息,应该是AIX5.3的“误报”(至少在5300-08-01上是这样,AIX6不会)可以不用理会。
4.确认生效
# 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
