Ip Redirects Enable; Ip Ttl-Expires Enable - HPE FlexFabric 5950 Series Command Reference Manual

Usage guidelines
Use this feature on a multichassis IRF fabric to improve fragment reassembly efficiency. This feature
enables a subordinate to reassemble the IPv4 fragments of a packet if all the fragments arrive at it. If
this feature is disabled, all IPv4 fragments are delivered to the master device for reassembly. The
feature applies only to fragments destined for the same subordinate.
Examples
# Enable IPv4 local fragment reassembly.
<Sysname> system-view
[Sysname] ip reassemble local enable

Usage guidelines
ICMP redirect messages simplify host management and enable hosts to gradually optimize their
routing tables.
A host that has only one route destined for the default gateway sends all packets to the default
gateway. The default gateway sends an ICMP redirect message to inform the host of a correct next
hop by following these rules:
•
The receiving and sending interfaces are the same.
•
The selected route is not created or modified by any ICMP redirect messages.
•
The selected route is not destined for 0.0.0.0.
•
There is no source route option in the received packet.
Examples
# Enable sending ICMP redirect messages.
<Sysname> system-view
[Sysname] ip redirects enable
