drIpInterfaceIcmpRedirects
Module: CROUTE-MIB
OID (symbolic): CROUTE-MIB::drIpInterfaceIcmpRedirects
OID (numeric): 1.3.6.1.4.1.81.31.6.1.1.14
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: enable - enable the sending of redirect messages if the router is forced to re-send a packet through the same interface on which it was received. disable - disable the sending of redirect messages on this interface.
What is drIpInterfaceIcmpRedirects?
This setting enables or disables the router sending ICMP redirect messages on this interface when it has to re-send a packet back out the same interface it arrived on. Admins often disable this on interfaces facing untrusted networks since ICMP redirects can be abused to manipulate host routing tables. For example, disabling drIpInterfaceIcmpRedirects on an internet-facing interface prevents the router from emitting redirect messages that a malicious host could otherwise leverage.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.81.31.6.1.1.14 snmpwalk -v2c -c public <target> CROUTE-MIB::drIpInterfaceIcmpRedirects
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.81.31.6.1.1.14.1 snmpget -v2c -c public <target> CROUTE-MIB::drIpInterfaceIcmpRedirects.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.81.31.6.1.1.14.1 i <value>
