[Babel-users] filtering harder?

[Dave Taht]

since I just finished rebuilding that crashed router I mentioned,
and this time I am doing static routing assignment, I am curious
if it is possible to suppress several p2p routes on it.

The relevant portion of the routing table on the next node over:

The main route (an ip address got via dhcp to the new router)

172.21.2.21 via 172.21.2.21 dev eth0  proto 42 onlink

A covering route added on the new router (via /etc/network/interfaces
up command)

ip route add unreachable 172.21.128.0/20 proto static

and visible this way elsewhere:

172.21.128.0/20 via 172.21.2.21 dev eth0  proto 42 onlink

A babel enabled node on the other side of the link:

172.21.128.10 via 172.21.2.21 dev eth0  proto 42 onlink

Three of the other interfaces on that router that are up.

172.21.128.1 via 172.21.2.21 dev eth0  proto 42 onlink
172.21.129.1 via 172.21.2.21 dev eth0  proto 42 onlink
172.21.130.1 via 172.21.2.21 dev eth0  proto 42 onlink

It seems to me I should be able to live without these last
three routes somehow.

The debian /etc/default/babel file for the command line

# List of interfaces on which the protocol should operate
INTERFACES="eth0 eth1 eth2 eth3"

# Additional arguments
DAEMON_ARGS="-l -z 3 -c /etc/babeld.conf -S /var/lib/babeld/state"

The babeld.conf:

redistribute ip 0.0.0.0/0 le 0 deny
redistribute ip ::/0 le 0 deny
redistribute ip ::/61 le 61 allow
redistribute ip 0.0.0.0/0 le 20 allow
