Read the interface IP bound to the VPN-instance via OID

1.3.6.1.2.1.4.20.1.1 The node can read all interface IPs belonging to the public network instance but cannot read the interface addresses bound to the VPN-instance

1.3.6.1.4.1.25506.2.67.1.1.2.1.4 The return value of the node is the interface address mask, and the OID index contains the interface address

Take the following configuration on the device as an example

[H3C]dis ip int brief

*down: administratively down

(s): spoofing  (l): loopback

Traverse the node 1.3.6.1.4.1.25506.2.67.1.1.2.1.4. The OID indexes 5121, 5127, and 5128 are interface indexes. You can view the correspondence between interface indexes and interface names via 1.3.6.1.2.1.2.2.1.2. The read result matches the address configured on the device.
