Re: Importing kernel routes

20 Oct 2009

      Hello Ondrej,
...
Here is the patch. It allows ti import 'onlink' non-neighbor 
routes from kernet table.
Thanks! It works fine.

Currently I try to exchange routes between a Mikrotik Router board and a
linux machine without using BIRD's filters. Is there a way to import a Linux
routing table e.g. #230 for redistribution by BGP4 and importing routes
coming via BGP4 to the Linux routing table e.g. #170 without using filters?

With my current config the BIRD will try to write back the routes from linux
table #230 to linux table #170, since I copy table amprnet to table hamnet:

table hamnet;
table amprnet;
protocol kernel kern1 {
        table amprnet;
        learn;                  # Learn all alien routes from the kernel
        scan time 20;           # Scan kernel routing table every 20 seconds
        export all;             # Default is export none
        kernel table 230;       # Kernel table to synchronize with (default:
main)
}
protocol kernel kern2 {
        table hamnet;
        learn;                  # Learn all alien routes from the kernel
        scan time 20;           # Scan kernel routing table every 20 seconds
        export all;
        kernel table 170;       # Kernel table to synchronize with (default:
main)
}
protocol device {
        scan time 10;           # Scan interfaces every 10 seconds
}
protocol pipe pipe1 {
        table hamnet;
        peer table amprnet;
}
protocol bgp {
        table hamnet;
        local as 64620;
        neighbor 44.130.230.249 as 64626;
        export all;
        import all;
        next hop self;          # Disable next hop processing and always
advertise our local address as nexthop
        source address 44.130.230.250;  # What local address we use for the
TCP connection
}

I think this will be easy to solve with filters (if you can handle them :)).
Tnx,
Jann
