`distribute-list` can be applied to both incoming and outgoing data.
.. _ripng-route-map:
RIPng route-map
===============
Usage of *ripngd*'s route-map support.
Route-map statement (:ref:`route-map`) is needed to use route-map
functionality.
.. clicmd:: match interface WORD
This command match to incoming interface. Notation of this match is
different from Cisco. Cisco uses a list of interfaces - NAME1 NAME2 ...
NAMEN. Ripngd allows only one name (maybe will change in the future). Next -
Cisco means interface which includes next-hop of routes (it is somewhat
similar to "ipv6 next-hop" statement). Ripngd means interface where this route
will be sent. This difference is because "next-hop" of same routes which
sends to different interfaces must be different.
.. clicmd:: match ipv6 address WORD
.. clicmd:: match ipv6 address prefix-list WORD
Match if route destination is permitted by access-list/prefix-list.
.. clicmd:: match metric (0-4294967295)
This command match to the metric value of RIPng updates. For other protocol
compatibility metric range is shown as (0-4294967295). But for RIPng protocol
only the value range (0-16) make sense.
.. clicmd:: set ipv6 next-hop local IPV6_ADDRESS
Set the link-local IPv6 nexthop address.
.. clicmd:: set metric (1-16)
Set a metric for matched route when sending announcement. The metric value
range is very large for compatibility with other protocols. For RIPng, valid
metric values are from 1 to 16.
.. clicmd:: set tag (1-4294967295)
Set a tag on the matched route.
Sample configuration
