# 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.
