-define Package/babels/description
- Babel is a loop-avoiding distance-vector routing protocol roughly based
- on DSDV and AODV, but with provisions for link cost estimation and
- redistribution of routes from other routing protocols.
- While it is optimised for wireless mesh networks, Babel will also work
- efficiently on wired networks. It will generate between 1.2 and 2.4 times
- the amount of routing traffic that RIPng would generate, while
- never counting to infinity.
- This is experimental source routing branch, and should be only used if you
- know what you are doing.

-# babel config file
-#
-# This config file simply documents sample entries.
-# "redistribute" means: redistribute routes from other routing protocols
-# into babel. "local" means addresses assigned to local interfaces.
-#
-# You do not need to edit this file: you can use /etc/config/babeld
-# instead (sections "interface" and "filter"). Both files can be used
-# simultaneously (the rules of this file are executed first).
-
-# the default rules are:
-#
-## redistribute local
-## redistribute deny
-#
-# this says, redistribute local addresses but no other routes
-
-
-# redistribute IPv4 default route into babel
-## redistribute local ip 0.0.0.0/0 le 0 metric 128
-
-# same but for IPv6
-## redistribute local ip ::/0 le 0 metric 128
-
-
-# don't redistribute all local addresses, only selected ones
-# after the first line, the "deny" rules kicks in. After the "deny"
-# no redistribute local rules are going to match
-## redistribute local ip 192.160.4.0/24
-## redistribute local deny
-
-
-# Babel refuses to redistribute routes with a protocol number of "boot";
-# this is standard practice, and means that you cannot easily
-# redistribute the default route installed by dhcp. It is however
-# possible to redistribute such route by explicitly specifying "proto 3"
-# on the redistribute line.
-## redistribute ip 0.0.0.0/0 le 0 proto 3 metric 128

-From: Steven Barth <steven@midlink.org>
-Date: Tue, 18 Feb 2014 13:18:32 +0100
-Subject: [PATCH] Allow routes with source ::/128 for SAS on Linux
-
-Linux uses the source-address :: (unspecified) to lookup routes in the
-routing table for connections that are not bound to a specific source
-address (e.g. ping6 2001:db8::1). If all default routes are
-source-restricted a command like above will result in a "Permission
-denied" error and no packets are being sent. Adding a default route with
-source ::/128 avoids this issue.
-
-This patch excludes ::/128 from the "martian_prefix" check for source
-prefixes and thus allows such auxiliary routes to be distributed.
