ZXR10 5900E Series Configuration Guide (IPv6)
A router will periodically send RA packets and may also use them as a response to the RS
packets it has received from hosts. Each RA packet may also contain prefix information,
link configuration information and IPv6 protocol parameters. It indicates the existence of
routers, and routers can forward the packet. The RA packet carries the information of the
routers. Such information helps a host make the next judgment for the packet to be sent.
The host discovers available routers through the RA packet and constructs a list of all the
discovered routers as the default router list.
A host may send an RS packet to inquire router configuration information and router-related
information. A time interval for consecutively sending RA packets has been set on each
router. The interval ranges from several seconds to several minutes. In order to avoid
long-time waiting before the configuration information is obtained and the communication
starts, the host may integrate the sending of RS packets as a part of its startup process.
A node can send an NS packet to interpret the link layer address of another node so as to
verify the reachability of that node and the address uniqueness of a specific link.
A node can send an NA packet as the response to an NS packet. It will also send
unsolicited NA packets to notify its own link layer address changes to other nodes.
2.2 Configuring NDP
To configure NDP, perform the following steps.
Step
Command
Function
1
ZXR10(config)#
interface
<
interface-name
>
Enters the interface
configuration mode.
ZXR10(config-if-interface-name)#
ipv6 nd
managed-config-flag
Sets the managed-config-flag
field of the RA packets sent on
the interface, that is, sets the
value of M bit in the packets to
1.
2
ZXR10(config-if-interface-name)#
no ipv6 nd
managed-config-flag
Clears the settings of the
managed-config-flag field and
restores the default value.
ZXR10(config-if-interface-name)#
ipv6 nd
other-config-flag
Sets the other-config-flag field
of the RA packets sent on the
interface, that is, sets the value
of 0 bit in the packets to 1.
3
ZXR10(config-if-interface-name)#
no ipv6 nd
other-config-flag
Clears the settings of the
other-config-flag field and
restores the default value.
