关于tunnel的建立，问什么添加不了路由呢

[baidu_41598605]

服务器 一 隧道ip

tun1: flags=209<UP,POINTOPOINT,RUNNING,NOARP> mtu 1480
inet 10.10.30.10 netmask 255.255.255.255 destination 121.46.234.115
inet6 fe80::200:5efe:79c9:606f prefixlen 64 scopeid 0x20<link>
tunnel txqueuelen 1000 (IPIP Tunnel)
RX packets 149 bytes 35664 (35.6 KB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 1358 bytes 188548 (188.5 KB)
TX errors 28 dropped 0 overruns 0 carrier 0 collisions 0

服务器二 隧道ip
tun1: flags=209<UP,POINTOPOINT,RUNNING,NOARP> mtu 1480
inet 10.10.30.9 netmask 255.255.255.255 destination 121.201.96.111
inet6 fe80::200:5efe:792e:ea73 prefixlen 64 scopeid 0x20<link>
tunnel txqueuelen 1000 (IPIP Tunnel)
RX packets 1358 bytes 188548 (188.5 KB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 149 bytes 35664 (35.6 KB)
TX errors 28 dropped 0 overruns 0 carrier 0 collisions 0

互相能ping通
root@ubuntu:~# ping 10.10.30.9
PING 10.10.30.9 (10.10.30.9) 56(84) bytes of data.
64 bytes from 10.10.30.9: icmp_seq=1 ttl=64 time=33.1 ms

服务器一上加路由没问题

root@ubuntu:~# /sbin/route add -net 193.57.218.0/24 gw 10.10.30.9
root@ubuntu:~#


服务器二上加路由报错
/sbin/route add -net 193.57.218.0/24 gw 10.10.30.10
SIOCADDRT: Network is unreachable

哪位大侠给解决一下。。。。。。。

同一网段，走两个不同的网关？人格分裂吗

[cqyy725]

不好意思，刚刚没看清楚，先检查本身的路由情况，删除重复网段的路由，再用ip route 设置

[baidu_41598605]

和加同一段地址没关系， 我现在是路由加不进去， 网络不可达， 10.10.30.9和10.10.30.10现在是互通的。

root@ubuntu:~# tracepath 10.10.30.9
1?: [LOCALHOST] pmtu 1480
1: 10.10.30.9 33.241ms reached
1: 10.10.30.9 33.470ms reached
Resume: pmtu 1480 hops 1 back 1

为什么添加不了路由，比较奇怪！！！！
