Problem Description

During the process of configuring the NNI interface of MSTP+FeatureOSN3500, configure the IP address of port 1 of slot 2PEGS2 to be 172.172.0.1, and configure the IP address of port 1 of slot 3PEGS2 to be 172.172.0.2, with subnet masks 255.255.255.252, and the network administrator prompts that the operation is partially successful, and the configuration can't be sent down.

Alarm message

None

Processing

Configure the IP address of port 1 of PEGS2 in slot 2 as 172.172.0.1, and configure the IP address of port 1 of PEGS2 in slot 3 as 172.172.0.9, and the configuration is issued successfully;

Root Cause

In the current related information, it is suggested that the port IP of the same single board cannot be configured as the same network segment, 172.172.0.1, and 172.172.0.2 belongs to the same network segment, although this configuration is on a different single board, does it also exist that the same network element cannot be configured with the same IP of the same address segment?

Suggestions and Summary

Except for the NNI configuration of the MSTP+ feature as suggested in the related information, the port IPs of the same single board cannot be configured as the same network segment, nor can the port IPs of the same network element be configured as the same network segment.
