路由顺序重要吗?
> route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
123.x.x.151 0.0.0.0 255.255.255.255 UH 0 0 0 vmbr0
123.x.x.154 0.0.0.0 255.255.255.255 UH 0 0 0 vmbr0
123.x.x.128 0.0.0.0 255.255.255.224 U 0 0 0 vmbr0
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 vmbr1
0.0.0.0 123.x.x.129 0.0.0.0 UG 0 0 0 vmbr0
是否与以下内容相同:
> route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
123.x.x.128 0.0.0.0 255.255.255.224 U 0 0 0 vmbr0
123.x.x.151 0.0.0.0 255.255.255.255 UH 0 0 0 vmbr0
123.x.x.154 0.0.0.0 255.255.255.255 UH 0 0 0 vmbr0
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 vmbr1
0.0.0.0 123.x.x.129 0.0.0.0 UG 0 0 0 vmbr0
?
区别在哪里
123.x.x.128 123.x.x.129 255.255.255.224 U 0 0 0 vmbr0
高于
123.x.x.151 0.0.0.0 255.255.255.255 UH 0 0 0 vmbr0
因此,如果我发送123.x.x.151
到哪里去:
- the routed way over `123.x.x.129`, because it matches the `123.x.x.128` rule, or
- the direct way using the arp table, because it matches the `123.x.x.151` rule
