Note:
Throughout this chapter, the term router refers to either a router in a general sense or a
Layer 3 switch running routing protocols.
1.1 Introduction to IPv6 Static Routing
Static routes are special routes that are manually configured by network administrators.
These manually configured static routes work well in simple networks. Configuring and
using them properly can improve the performance of networks and can guarantee
enough bandwidth reserved for important applications.
However, static routes also have their downside: network failure or topology changes
could introduce unreachable routes that lead to network disconnection. Such scenarios
require the network administrators to manually configure and modify the static routes.
1.1.1 Features and Functionalities of IPv6 Static Routes
Similar to IPv4 static routes, IPv6 static routes work well in simple IPv6 network
environments.
Their major difference lies in the destination and the next hop addresses. IPv6 static
routes use IPv6 addresses whereas IPv4 static routes use IPv4 addresses.
1.1.2 Default IPv6 Route
An IPv6 static route that has the destination address configured as “::/0” (indicating a
prefix length of 0) is the default IPv6 route. If the destination address of an IPv6 packet
does not match any entries in the routing table, this default route will be used to forward
the packet.

1.2 Configuring IPv6 Static Routes
In small IPv6 network environments, IPv6 static routes can be used to achieve network
connectivity. In comparison to dynamic routes, it helps to save network bandwidth.

When configuring RIPng, go to these sections for information you are interested in:
z Introduction to RIPng

z Configuring RIPng Advanced Functions
z Optimizing the RIPng Network
z RIPng Configuration Example
Note:
The term “router” in this document refers to a router in a generic sense or a Layer 3
switch.
2.1 Introduction to RIPng
RIP next generation (RIPng) is an extension of RIP-2 for IPv4. Most RIP concepts are
applicable in RIPng.
RIPng for IPv6 made the following changes to RIP:
z UDP port number: RIPng uses UDP port 521 for sending and receiving routing
information.
z Multicast address: RIPng uses FF02:9 as the link-local multicast address.
z Destination Prefix: 128-bit destination address prefix.
z Next hop: IPv6 address in 128-bit.
z Source address: RIPng uses FE80::/10 as the link-local source address
2.1.1 RIPng Working Mechanism
RIPng is a routing protocol based on the distance vector (D-V) algorithm. RIPng uses
UPD packets to exchange routing information through port 521.
RIPng uses a hop count to measure the distance to a destination. The hop count is
referred to as metric or cost. The hop count from a router to a directly connected
network is 0. The hop count from one router to another router is 1, and so on. When the
hop count is greater than or equal to 16, the destination network or host is unreachable.
By default, the routing update is sent every 30 seconds. If the router receives no routing
update from a neighbor after 180 seconds, the routes learned from the neighbor are
Operation Manual – IPv6 Routing
H3C S5500-SI Series Ethernet Switches Chapter 2
IPv6-RIPng Configuration
2-2
31
considered as unreachable. After another 240 seconds, if no routing update is received,
the router will remove these routes from the routing table.
RIPng supports Split Horizon and Poison Reverse to prevent routing loops, and route
redistribution.
Each RIPng router maintains a routing database, including route entries of all
reachable destinations. A route entry contains the following information:
z Destination address: IPv6 address of a host or a network.
z Next hop address: IPv6 address of a neighbor along the path to the destination.
z Egress interface: Outbound interface that forwards IPv6 packets.
z Metric: Cost from the local router to the destination.
z Route time: Time that elapsed since a route entry is last changed. Each time a
route entry is modified, the routing time is set to 0.
z Route tag: Identifies the route, used in routing policy to control routing.
2.1.2 RIPng Packet Format
I. Basic format
A RIPng packet consists of a header and multiple Route Table Entries (RTEs). The
maximum number of RTEs in a packet is determined by the interface MTU value.
Figure 2-1 shows the basic packet format of RIPng.

command must be zeroversion
Route Table Entry N (20 octets)
Route Table Entry 1 (20 octets)

z Command: Type of message. 0x01 indicates Request, 0x02 indicates Response.
z Version: Version of RIPng. It can only be 0x01 currently.
z RTE: Route table entry, 20 bytes for each entry.
II. RTE format
There are two types of RTE in RIPng.
z Next hop RTE: Defines a next hop IPv6 address
z IPv6 prefix RTE: Describes the destination IPv6 address and metric in the RIPng
routing table.
Figure 2-2 shows format of the next hop RTE:

z Route tag: Route tag.
z Prefix len: Length of the IPv6 address prefix.
z Metric: Cost of a route.
2.1.3 RIPng Packet Processing Procedure
I. Request packet
When a RIPng router first starts or needs to update some entries in its routing table,
generally a multicast request packet is sent to ask for needed routes from neighbors.
The receiving RIPng router processes RTEs in the request. If there is only one RTE
with the IPv6 prefix and prefix length both being 0, and with a metric value of 16, the
RIPng router will respond with the entire routing table information in response
messages. If there are multiple RTEs in the request message, the RIPng router will
examine each RTE, update its metric, and send the requested routing information to
the requesting router in the response packet.
II. Response packet
The response packet containing the local routing table information is generated as:
z A response to a request
z An update periodically
z A trigged update caused by route change
Operation Manual – IPv6 Routing
H3C S5500-SI Series Ethernet Switches Chapter 2
IPv6-RIPng Configuration
2-4
After receiving a response, a router checks the validation of the response before adding
the route to its routing table, such as whether the source IPv6 address is the link-local
address, whether the port number is correct. The response packet failed the check will
be discarded.

2.2 Configuring RIPng Basic Functions
In this section, you are presented with the information to configure the basic RIPng
features.
You need to enable RIPng first before configuring other tasks, but it is not necessary for
RIPng related interface configurations, such as assigning an IPv6 address.
2.2.1 Configuration Prerequisites
Before the configuration, accomplish the following tasks first:
z Enable IPv6 packet forwarding.
z Configure an IP address for each interface, and make sure all nodes are
reachable.

RIPng route.
2.3 Configuring RIPng Advanced Functions
This section covers the following topics:
z Configuring an Additional Routing Metric
z Configuring RIPng Route Summarization
z Advertising a Default Route
z Configuring a RIPng Route Filtering Policy
z Configuring a RIPng Priority
z Configuring RIPng Route Redistribution
Before the configuration, accomplish the following tasks first:
z Configure an IPv6 address on each interface, and make sure all nodes are
reachable.
z Configure RIPng basic functions
z Define an IPv6 ACL before using it for route filtering. Refer to ACL configuration for
related information.
z Define an IPv6 address prefix list before using it for route filtering.
2.3.1 Configuring an Additional Routing Metric
An additional routing metric can be added to the metric of an inbound or outbound RIP
route, namely, the inbound and outbound additional metric.
The outbound additional metric is added to the metric of a sent route, the route’s metric
in the routing table is not changed.
The inbound additional metric is added to the metric of a received route before the route
is added into the routing table, so the route’s metric is changed.
Follow these steps to configure an inbound/outbound additional routing metric:
