What is the difference between MGMT IP and egress ip on Ruijie Cloud？

Mgmt IP (Management IP)

Definition:

The
mgmt IP
is the IP address assigned to a management interface on a network device,such as a router, switch, firewall, or server. This interface is specificallydesigned for remote administration and monitoring of the device.

Usage:
It allows administrators to connect to the device via SSH, Telnet, or web-basedinterfaces for configuration, updates, and troubleshooting.
Typically, the
mgmt IP
is part of a separate management VLAN or subnet to isolate management traffic from production traffic.

Example: An administrator might use the
mgmt IP
address
192.168.1.1
to log into a router's command line interface orweb interface for configuration purposes.

Egress IP

Definition:

The
egress IP
is the IP address that represents the source IP address of outgoing packets leaving a network or a device. It is often associated with Network Address Translation (NAT), where multiple internal IP addresses are mapped to asingle public IP address.

Usage:

When a packet leaves a network device or a NAT gateway, the original source IP address within the private network is replaced with the
egress IP
.

This is common in environments where multiple devices share a single public IPaddress for external communications.

Example:

If a company uses NAT to map all internal hosts to a single public IP address
203.0.113.1
, then all outgoing traffic from these hosts will show
203.0.113.1
as the source IP address.

Summary

mgmt IP is primarily used for managing and monitoring network devices.

egress IP is used to identify the source IP address of packets exiting a network or adevice when NAT is employed.

These two types of IP addresses serve very different functions and are usually distinct. While they can be the same insome specific configurations, especially in small networks or with certain types of devices, they are typically kept separate for security and operational reasons.
