RIPng |
RIPng functions the same and offers the same benefits as RIP in IPv4. RIP enhancements for IPv6, detailed in RFC 2080, include support for IPv6 addresses and prefixes, and the use of all-RIP-routers multicast group address as the destination address for RIP update messages. This module describes how to configure Routing Information Protocol for IPv6. RIPng process maintains a local routing table, referred to as a RIB. The RIPng RIB contains a set of RIPng routes learned from all its neighboring networking devices.
10.1 RIPng Commands
The list of CLI commands for the configuration of RIPng is as follows:
10.1.1 ipv6 router rip
Enables RIPng and enters into the router configuration mode and the no form of the command disables RIPng on all the interfaces.
|
Mode
|
Global Configuration
|
|
Example
|
SEFOS(config)# ipv6 router rip
|
|
Notes
|
Before configuring the router to run RIPng, the ipv6 unicast-routing must be enabled globally, and IPv6 must be enabled on the interface in which RIPng is to be processed.
|
- ipv6 rip enable - Enables IPv6 RIP processing on an interface that has not been configured with an explicit IPv6 address
10.1.2 ipv6 router rip - name
Enables RIPng and enters into the router configuration mode. The no form of the command disables RIPng on all the interfaces. This command operates similar to that of the command ipv6 router rip.
|
Syntax Description
|
name - Specific RIPng routing process. This feature is ignored during the command execution.
|
|
Mode
|
Global Configuration
|
|
Example
|
SEFOS(config)# ipv6 router rip router1
|
|
Notes
|
Before configuring the router to run RIPng, the ipv6 unicast-routing must be enabled globally, and IPv6 must be enabled on the interface in which RIPng is to be processed.
|
10.1.3 ipv6 split-horizon
Enables the split-horizon updates and the no form of the command disables the split-horizon updates.
|
Mode
|
Interface Configuration
|
|
Example
|
SEFOS(config-if)# ipv6 split-horizon
|
|
Notes
|
The value split-horizon denotes that split-horizon algorithm must be applied in the response packets that are going out.
|
- show ipv6 rip - Displays IPv6 local RIB and routing protocol information
10.1.4 ipv6 rip enable
Enables RIP routing and the no form of the command disables the RIP routing.
|
Mode
|
Interface Configuration
Applicable only in the VLAN interface mode.
|
|
Example
|
SEFOS(config-if)# ipv6 rip enable
|
- show ipv6 rip - Displays IPv6 Local RIB and routing protocol information
10.1.5 ipv6 rip name enable
Enables the specified RIPng routing process on an interface. The no form of the command disables the specified routing process on an interface. This command operates similar to that of the command ipv6 rip enable.
|
Syntax Description
|
name - Specific RIPng routing process. This feature is ignored during the command execution.
|
|
Mode
|
Interface Configuration
Applicable in the VLAN Interface mode only.
|
|
Example
|
SEFOS(config-if)# ipv6 rip name enable
SEFOS(config-if)# no ipv6 rip name enable
|
- show ipv6 rip - Displays IPv6 local RIB and routing protocol information
10.1.6 ipv6 rip default-information - originate | only
Originates the IPv6 default route into the specified RIP routing process updates, sent from the specified interface. This command operates similar to that of the command ipv6 rip default-information originate.
| Note - The routing process ignores all default routes received on any interface, after originating the IPv6 default route out of any interface to avoid routing loops.
|
ipv6 rip process-name default-information {originate | only } [metric value]
|
|
Syntax Description
|
process-name - Specific RIPng routing process. This feature is ignored during the command execution.
originate - Default route is originated in addition to all other routes in the updates sent from the interface.
only - Default route is originated while suppressing all other routes in the updates sent from the interface.
metric - Metric to be used for redistributed routes.
|
|
Mode
|
Interface Configuration
Applicable only in the VLAN interface mode.
|
|
Example
|
SEFOS(config-if)# ipv6 rip process1 default-information originate
|
- show ipv6 rip - Displays IPv6 local RIB and routing protocol information
10.1.7 ipv6 rip metric-offset
Adjusts default metric increment.
ipv6 rip metric-offset 1-15
|
|
Mode
|
Interface Configuration
|
|
Example
|
SEFOS(config-if)# ipv6 rip metric-offset 6
|
|
Notes
|
- The ipv6 rip metric-offset command is used in conjunction with the redistribute router configuration command to cause the current routing protocol to use the same metric value for all redistributed routes.
- The maximum metric that RIP can advertise is 16, and a metric of 16 denotes a route that is unreachable.
|
- show ipv6 rip - Displays IPv6 local RIB and routing protocol information
10.1.8 redistribute
Enables redistribution of IPv6 prefix from another protocol into RIPng. The no form of the command disables redistribution of IPv6 prefix from another protocol into RIPng.
redistribute {static | connected | ospf} metric 0-16
|
no redistribute {static | connected | ospf}
|
|
Syntax Description
|
static - Statically configured routes to advertise in the RIPng process.
connected - Connected routes to advertise in the RIPng process.
ospf - OSPF routes to advertise in the RIPng process.
metric - Routing metric associated with the route.
|
|
Mode
|
Router Configuration
|
|
Example
|
SEFOS(config-router)# redistribute static metric 6
|
- show ipv6 rip - Displays IPv6 local RIB and routing protocol information
10.1.9 distribute prefix
Enables filter network in routing updates sent or received and the no form of the command disables Filter network in routing updates sent or received.
distribute prefix ipv6_addr {in | out}
|
no distribute prefix ipv6_addr {in | out}
|
|
Syntax Description
|
ipv6-addr - IPv6 Address
in - Filter network in routing updates received
out - Filter network in routing updates sent out
|
|
Mode
|
Router Configuration
|
|
Example
|
SEFOS(config-router)# distribute prefix fe80::208:2ff:fe02:408 in
|
|
Notes
|
- Filtering is controlled by distribute lists. Input distribute lists control route reception and input filtering is applied to advertisements received from neighbors. Only those routes that pass input filtering are inserted in the RIP local routing table and become candidates for insertion into the IPv6 routing table.
- Output distribute lists control route advertisement. Output filtering is applied to route advertisements sent to neighbors. Only those routes passing output filtering will be advertised.
|
10.1.10 debug ipv6 rip
