This enhancement to quagga (which is in cerowrt-sugarland) adds back an ability we lost in converting from the original babeld.
I used it to allow ipv6 traffic to be routed over ipv4 natted links in the bloatlab. (by blocking ipv4 distribution over the shared external wire but allowing ipv6) No doubt there are other uses. One of my thoughts with this technology is to be able to share your ipv6 routes/addresses with your neighbor, be your ipv6 connection be native or tunnelled. ---------- Forwarded message ---------- From: Matthieu Boutier <[email protected]> Date: Sun, Sep 16, 2012 at 3:27 PM Subject: [Babel-users] babeld/quagga: v4 and v6 distribution To: [email protected] Hello, It's now possible to distribute both v4 and v6 on quagga's babeld in quagga RE-testing-0.99, but the syntax is affected. The definition of an access/prefix-list doesn't differ: the kind (v4 or v6) is explicit, e.g. : access-list toto deny any ipv6 access-list toto deny any (note that you have in this example the same name ("toto") for two different lists: one v4, the other v6) You must specified v4 or v6 for the redistribution: distribute-list toto /* will distribute the v4 "toto" list */ ipv6 distribute-list toto /* will distribute the v6 "toto" list */ For ripng, which use only v6, you can continue to use the v4 syntax : distribute-list toto /* will distribute the v6 list */ ipv6 distribute-list toto /* same */ Here is a complete example: password zebra enable password zebra router babel network eth0 distribute-list global_ipv4 in eth0 distribute-list local_ipv4 out eth0 ipv6 distribute-list local_ipv6 out eth0 redistribute kernel redistribute connected redistribute static redistribute ripng access-list local_ipv4 permit 1.2.3.0/23 access-list local_ipv4 deny any access-list global_ipv4 deny 1.2.0.0/16 access-list global_ipv4 permit any ipv6 access-list local_ipv6 permit 2001:2:3:4::/64 ipv6 access-list local_ipv6 deny any log file /var/log/quagga/babeld.log -- Matthieu _______________________________________________ Babel-users mailing list [email protected] http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/babel-users -- Dave Täht http://www.bufferbloat.net/projects/cerowrt/wiki - "3.3.8-17 is out with fq_codel!" _______________________________________________ Cerowrt-devel mailing list [email protected] https://lists.bufferbloat.net/listinfo/cerowrt-devel
