netinet.icmp.redirect

Severity

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.

Syslog Message

Received %lu ICMPv4 redirect messages for IPspace "%s".

Parameters

no_of_redirects (LONGINT): Total number of ICMPv4 redirects received for the specific IPspace.
ipspace (STRING): The IPspace for which the redirect packets are received.
