[Use Cases]

Section titled “ipv6 ripng split-horizon [poisoned-reverse]”[Command] ipv6 ripng split-horizon [poisoned-reverse]
[Purpose] Configure horizontal cutting with RIPng enabled on the interface, and also enable both horizontal cutting and toxicity reversal simultaneously. Horizontal segmentation: Do not re advertise the route from the receiving interface to prevent the router from re advertising the learned route back to the source. This feature is enabled by default. Toxicity reversal: For routes learned from a certain interface, they are still advertised back from that interface, but the metric value is set to 16 (unreachable), which means “poisoning” the route. It belongs to the advanced level of horizontal segmentation. This function needs to be manually activated.

sonic(config)# interface ethernet 3sonic(config-if-3)# ipv6 ripng split-horizon poisoned-reverserouter ripng [vrf
Section titled “router ripng [vrf”[Command] router ripng [vrfname**]**
[Purpose] Enable RIPng routing process, which is a prerequisite for all other RIPng configurations and supports specifying specific VRFs afterwards.

sonic(config)# router ripngsonic(config-router)#network {
Section titled “network {”[Command] network {X:X::X:X/M****|ethernetinterface_num|vlanvlan_id|link-aggregationlag_id}**
[Purpose] Enable RIPng based on network address or interface type. When specifying a network address, all interfaces with IP addresses within the specified network will start sending and receiving RIPng messages. When specifying the interface type, RIPng messages will be sent and received on the specified interface.
[Parameter]
| Parameter | Description |
|---|---|
| X:X::X:X/M | Configure IPv6 addresses with masks to specify the declared network segment, such as 2005::10/96 |
| interface_num | The ID of the physical interface, ranging from 1 to 16 |
| vlan_id | VLAN ID, ranging from 1 to 4096 |
| lag_id | The ID of lag, ranging from 1 to 9999 |

Section titled “passive-interface {default|ethernet”[Command] passive-interface {default|ethernetinterface_num**|vlanvlan_id|link-aggregationlag_id}**
[Purpose] Set a passive interface that only receives RIPng updates and does not send multicast/broadcast updates (but sends unicast updates to neighbors specified by the neighbor command). When set to default, it applies to all interface types within the RIPng.
[Parameter]
| Parameter | Description |
|---|---|
| interface_num | The ID of the physical interface, ranging from 1 to 16 |
| vlan_id | VLAN ID, ranging from 1 to 4096 |
| lag_id | The ID of lag, ranging from 1 to 9999 |

Section titled “redistribute”[Command] redistributeprotocol
[Purpose] Perform route redistribution by introducing routes from other routing protocols (such as BGP, OSPF, direct connection, static, etc.) into RIPng.
[Parameter]
| Parameter | Description |
|---|---|
| protocol | Specify the routing protocol type to be introduced, such as connected, static, BGP, OSPF, etc |

sonic(config)# router ripngsonic(config-router)# redistribute staticdefault-information originate
Section titled “default-information originate”[Command] default-information originate
[Purpose] Inject a default route (::/0) into the RIPng network, usually requiring the router to already have a default route.

[Use Cases]
sonic(config)# router ripngsonic(config-router)# default-information originate[Command] routeX:X::X**:X***/M***
[Purpose] Create static routes that only exist within RIPng processes.

Section titled “ipv6 distribute-list prefix”[Command] ipv6 distribute-list prefixstring**[in|out] {ethernetinterface_num|vlanvlan_id|link-aggregationlag_id}**
[Purpose] Set the distribution list of RIPng and use access control lists or prefix lists to filter route updates in the input or output direction of the interface. In filters routes learned from neighbors, and out filters routes declared to neighbors. Can be applied to global or specific interfaces.
[Parameter]
| Parameter | Description |
|---|---|
| String | Prefix list name |
| interface_num | The ID of the physical interface, ranging from 1 to 16 |
| vlan_id | VLAN ID, ranging from 1 to 4096 |
| lag_id | The ID of lag, ranging from 1 to 9999 |

Section titled “aggregate-address”[Command] aggregate-addressX:X::X**:X***/M***
[Purpose] Summarize more specific routes and announce the summarized routes; Can reduce routing table size and update message overhead.

Section titled “default-metric”[Command] default-metricvalue
[Purpose] Set the default metric value for redistributing incoming routes, which defaults to 1 and does not affect the redistribution metric of directly connected routes

Section titled “timers basic”[Command] timers basicupdate timeout garbage
[Purpose] Adjust the key timer of RIPng. Update: The time interval for sending the complete routing table (default is 30 seconds). TIMEOUT: Route failure timeout (default 180 seconds). GARBAGE: Garbage collection time before the route is removed (default is 120 seconds).
[Parameter]
| Parameter | Description |
|---|---|
