NOTICE
- Description
-
This message occurs when an ICMPv4 redirect message is received. The redirect might be received due to either a misconfigured route or a man-in-the-middle ICMP redirect attack.
- Corrective Action
-
When enabled, ICMP redirects can be disabled using the "network tuning icmp modify -is-drop-redirect-enabled true" command. However, disabling ICMP redirects might lead to connectivity problems or longer delays of data transfers.

- Parameters
-
no_of_redirects (LONGINT): Total number of ICMPv4 redirects received for the specific IPspace.
