Specifying The Source Address For Icmpv6 Packets; Enabling Ipv6 Local Fragment Reassembly - HPE FlexNetwork 10500 Series Configuration Manual

•
The interface receiving the packet is the interface forwarding the packet.
•
The selected route is not created or modified by any ICMPv6 redirect messages.
•
The selected route is not a default route.
•
The forwarded packet does not contain the routing extension header.
The ICMPv6 redirect feature simplifies host management by enabling hosts that hold few routes to
optimize their routing table gradually. However, to avoid adding too many routes on hosts, this
feature is disabled by default.
To enable sending ICMPv6 redirect messages:
Step
1. Enter system view.
2. Enable sending ICMPv6 redirect
messages.

Specifying the source address for ICMPv6 packets

Perform this task to specify the source IPv6 address for outgoing ping echo requests and ICMPv6
error messages. It is a good practice to specify the IPv6 address of the loopback interface as the
source IPv6 address. This feature helps users to easily locate the sending device.
If you specify an IPv6 address in the ping command, ping echo requests use the specified address
as the source IPv6 address. Otherwise, ping echo requests use the IPv6 address specified by the
ipv6 icmpv6 source command.
To specify the source IPv6 address for ICMPv6 packets:
Step
1. Enter system view.
2. Specify an IPv6 address as
the source address for
outgoing ICMPv6 packets.

Enabling IPv6 local fragment reassembly

Perform this task to enable the local reassembly feature for IPv6 fragments that are destined for the
local device. This feature improves IPv6 fragment reassembly performance.
(In standalone mode.) This feature enables the receiving LPU to reassemble the received IPv6
fragments instead of delivering them to the active MPU for reassembly. It applies only to fragments
destined for the same LPU.
(In IRF mode.) This feature enables the receiving subordinate to reassemble the received IPv6
fragments instead of delivering them to the master for reassembly. It applies only to fragments
destined for the same subordinate.
To enable IPv6 local fragment reassembly:
Step
1. Enter system view.

Remarks
N/A
By default, sending ICMPv6
redirect messages is disabled.
Remarks
N/A
By default, the device uses the
IPv6 address of the sending
interface as the source IPv6
address for outgoing ICMPv6
packets.
