# RIPng

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

  Enable RIPng.

flush_timer TIME

  Set flush timer.

network NETWORK

  Set RIPng enabled interface by NETWORK.

network IFNAME

  Set RIPng enabled interface by IFNAME.

route NETWORK

  Set RIPng static routing announcement of NETWORK.

## ripngd Terminal Mode Commands

show ip ripng

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 10.0.0.0/8

      !
      router ripng
       distribute-list private in eth0
      !
      access-list private permit 10 10.0.0.0/8
      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
