ripngd supports the RIPng protocol as described in RFC 2080. It’s an IPv6 reincarnation of the RIP protocol.

Invoking ripngd

There are no ripngd specific invocation options. Common options can be specified (Common Invocation Options).

ripngd Configuration

Currently ripngd supports the following commands:

router ripng [vrf NAME]

Enable RIPng.

network NETWORK

Set RIPng enabled interface by NETWORK.

network IFNAME

Set RIPng enabled interface by IFNAME.


Set RIPng static routing announcement of NETWORK.

allow-ecmp [1-MULTIPATH_NUM]

Control how many ECMP paths RIPng can inject for the same prefix. If specified without a number, a maximum is taken (compiled with --enable-multipath).

ripngd Terminal Mode Commands

show ipv6 ripng [vrf NAME] status
show debugging ripng
debug ripng events
debug ripng packet
debug ripng zebra

ripngd Filtering Commands

RIPng routes can be filtered by a distribute-list.

distribute-list [prefix] LIST <in|out> IFNAME

You can apply access lists to the interface with a distribute-list command. If prefix is specified LIST is a prefix-list. If prefix is not specified then LIST is the access list name. in specifies packets being received, and out specifies outgoing packets. Finally if an interface is specified it will be applied against a specific interface.

The distribute-list command can be used to filter the RIPNG path. distribute-list can apply access-lists to a chosen interface. First, one should specify the access-list. Next, the name of the access-list is used in the distribute-list command. For example, in the following configuration eth0 will permit only the paths that match the route

router ripng
 distribute-list private in eth0
access-list private permit 10
access-list private deny any

distribute-list can be applied to both incoming and outgoing data.

Sample configuration

debug ripng events
debug ripng packet

router ripng
 network sit1
 route 3ffe:506::0/32
 distribute-list local-only out sit1

ipv6 access-list local-only permit 3ffe:506::0/32
ipv6 access-list local-only deny any
