摘要：在 NSX 路由排错时，可能需要在ESXi主机上分析DLR路由学习情况，此时必须通过ssh连接到主机用命令查看
操作步骤：
1、SSH 连接到 ESXi 主机
2、运行 net-vdr --instance -l 命令获取 DLR 的名称
[root@ESXi1:~] net-vdr --instance -l
VDR Instance Information :
Vdr Name: default+edge-cd4d8d68-9444-421d-9260-513106a2123d
Vdr Id: 0x00001392
Number of Lifs: 3
Number of Routes: 5
State: Enabled Universal Local-Egress
Controller IP: 10.10.50.20
Control Plane IP: 10.10.50.11
Control Plane Active: Yes
Num unique nexthops: 2
Generation Number: 0
Edge Active: No
3、运行net-vdr --route DLR_name -l 查看详细路由信息
[root@ESXi1:~] net-vdr --route default+edge-cd4d8d68-9444-421d-9260-513106a2123d -l
