+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 (:ref:`common-invocation-options`).

+
+ripngd Configuration
+====================
+
+Currently ripngd supports the following commands:
+
+.. clicmd:: router ripng
+
+   Enable RIPng.
+
+.. clicmd:: flush_timer TIME
+
+   Set flush timer.
+
+.. clicmd:: network NETWORK
+
+   Set RIPng enabled interface by NETWORK.
+
+.. clicmd:: network IFNAME
+
+   Set RIPng enabled interface by IFNAME.
+
+.. clicmd:: route NETWORK
+
+   Set RIPng static routing announcement of NETWORK.
+
+
+.. _ripngd-terminal-mode-commands:
+
+ripngd Terminal Mode Commands
+=============================
+
+.. clicmd:: show ip ripng
+
+.. clicmd:: show debugging ripng
+
+.. clicmd:: debug ripng events
+
+.. clicmd:: debug ripng packet
+
+.. clicmd:: debug ripng zebra
+
+
+ripngd Filtering Commands
+=========================
+
+RIPng routes can be filtered by a distribute-list.
+
+.. clicmd:: 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
+
+   .. code-block:: frr
+
+      !
+      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
+====================
+
+.. code-block:: frr
+
+   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
