Users Manual of CS-6306R
In normal cases, you are not recommended to change the default state unless you
are sure that the routes can be correctly declared after the state of your application
program is changed. If horizontal fragmentation is forbidden on a serial interface
that connects a packet switching network, you have to disable horizontal
fragmentation on routers of any related multicast group on a network.
53.1.3.11 Monitoring and Maintaining RIPng
Through monitoring and maintaining RIPng, you can get the statistic information of a network, including the
parameters of RIPng, the network usage information and the real communication-tracing information. This
kind of information can help users to judge the usage of network resources and solve network problems. From
the statistics information, you can also know the reachablity of a network node.
To display all kinds of statistics information, run the following commands in EXEC mode:
Command Purpose
show ipv6 rip instance-name
summary
Displays the total routing information
about a RIPng instance.
show ipv6 rip instance-name database
Displays all routes of a RIPng instance.
show ipv6 rip instance-name interface
Displays all interfaces that a RIPng
instance covers.
To trace the information about the routing protocols, run the following commands in EXEC mode:
Command Purpose
debug ipv6 rip instance-name database
Traces that a route of a RIPng instance
is added to removed from or changed
in a routing table.
debug ipv6 rip instance-name event
Traces the abnormity that occurs in the
running of a RIPng instance and the
whole process of redistributing a RIPng
instance.
debug ipv6 rip instance-name send
Traces the process that a RIPng
instance transmits packets.
debug ipv6 rip instance-name recv
Traces the process that a RIPng
instance receives packets.
debug ipv6 rip instance-name msg
Traces the important events that lead to
the termination of the startup of a
RIPng instance.
debug ipv6 rip instance-name all
Traces all the information about a
RIPng instance.
