The ICMPv6 redirect function 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 function
is disabled by default.
To enable sending ICMPv6 redirect messages:
Ste

Command Remarks
1. Enter system view.
system-view N/A
2. Enable sending ICMPv6 redirect
messages.
ipv6 redirects enable
By default, sending ICMPv6
redirect messages is disabled.
Specifying the source address for ICMPv6 packets
Perform this task to specify the source IPv6 address for outgoing ping echo request 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 locate the sending device easily.
If you specify an IPv6 address in the ping command, ping echo requests use the specified address as the
source IPv6 address rather than the IPv6 address specified by the ipv6 icmpv6 source command.
To specify the source IPv6 address for ICMPv6 packets:
Ste
p
Command Remarks
1. Enter system view.
system-view N/A
2. Specify an IPv6 address as the
source address for outgoing
ICMPv6 packets.
ipv6 icmpv6 source [ vpn-instance
vpn-instance-name ] ipv6-address
By default, the device uses the
IPv6 address of the sending
interface as the source IPv6
address for outgoing ICMPv6
packets.
Displaying and maintaining IPv6 basics
Execute display commands in any view and reset commands in user view.
Task Command
Display IPv6 FIB entries.
display ipv6 fib [ vpn-instance vpn-instance-name ] [ ipv6-address
[ prefix-length ] ]
Display IPv6 information about the
interface.
display ipv6 interface [ interface-type [ interface-number ] ] [ brief ]
Display IPv6 prefix information about the
interface.
display ipv6 interface interface-type interface-number prefix
Display neighbor information
(MSR2000/MSR3000).
display ipv6 neighbors { ipv6-address | all | dynamic | interface
interface-type interface-number | static | vlan vlan-id } [ verbose ]
Display neighbor information
(MSR4000).
display ipv6 neighbors { { ipv6-address | all | dynamic | static }
[ slot slot-number ] | interface interface-type interface-number |
vlan vlan-id } [ verbose ]
