Re: One router - Two ASN

24 Mar 2012

      Here is my config file:

log syslog all;

router id 91.aaa.aaa.1;

protocol device {
        scan time 15;
}

protocol kernel {
        export all;
        scan time 15;
}

protocol static {
        route 91.aaa.aaa.0/24 reject;
        route 91.kkk.kkk.0/22 reject;
}

filter bgp_out
{
    if net = 91.aaa.aaa.0/24 then accept;
    else reject;
}

protocol bgp bgp_bdi {
    description "BDI";
    import all;
    local as 57zzz;
    neighbor 83.bbb.bbb.21 as 12nnn;
    source address 83.bbb.bbb.22;
    export filter {
        if source = RTS_STATIC then {
            bgp_path.prepend(57zzz);
            accept;
        }
        reject;
    };
}

protocol bgp bgp_vop {
    description "Vop";
    import all;
    export filter {
        if source = RTS_STATIC then {
            accept;
        }
        reject;
    };
    local as 57zzz;
    neighbor 109.xxx.xxx.77 as 50yyy;
    source address 109.xxx.xxx.78;
    default bgp_local_pref 200;
}

Now I want add second ASN, which must communicate with 57zzz.

Hi.

How can I run two asn on one router?
Example:
ISP1 
     |
---------------
| AS1 - AS2 |
---------------
               |
            ISP2
ISP1 is connected to AS1, ISP2 is connected to AS2. How can I configure
connection AS1-AS2 with bgp protocol on localhost (neighbor ip and
source address)?
What about local option of bgp protocol?
