[Babel-users] openwrt babel configuration

[Dane Medic]

Hi Matthieu,

thank you for your answer. I think I don't know enough about babeld to
understand the info from the link you gave, but the configuration I have
pasted worked when I've connected the GW to wan port.

Anyway I have been googleing a bit more and I decided to use:
- on GW router
uci set babeld. at filter[2].type=redistribute
uci set babeld. at filter[2].ip=0.0.0.0/0
uci set babeld. at filter[2].proto=0
uci set babeld. at filter[2].action="metric 128"

instead of

uci set babeld. at filter[2].type=redistribute
uci set babeld. at filter[2].ip=0.0.0.0/0
uci set babeld. at filter[2].action=allow

- on 2ND router:
uci set babeld. at filter[2].type=redistribute
uci set babeld. at filter[2].ip=192.168.4.0/24
uci set babeld. at filter[2].proto=0
uci set babeld. at filter[2].action="metric 128"

instead of

uci set babeld. at filter[2].type=redistribute
uci set babeld. at filter[2].ip=192.168.4.0/24
uci set babeld. at filter[2].action=allow
---------

so both configurations are working for me so far, but I think many of us
users would be thankful if someone explained all this proto and le and ge
... switches. Maybe even on this wiki ->
http://wiki.openwrt.org/doc/uci/babeld
