./configure
make
sudo make install
That's it. By default, it went into /usr/local/. I have Debian 4 (Etch) with 2.6.8 kernel and a lot of development packages installed. The only thing I had to do was to add /usr/local/lib to /etc/ld.so.conf file and run /sbin/ldconfig.
Here is the setup
Now I need a valid configuration file for Quagga BGP. Adding 300000 network statements manually is not something system administrators do on Linux. Hence, here is the script
#!/usr/bin/perl
my $host="quagga-host"; #quagga router name
my $logpass="zebra"; #login password
my $enable="zebra"; #enable password
my $myasn="65099"; #local AS number
my $router_id="172.31.2.2"; #bgp router-id
my $remote_as="65001"; #remote-as number
my $remote_ip="172.31.2.1"; #BGP neighbor ip address
my $route_count=0;
my $max_routes=300000; #max number of routers to generate
open (BGPCONF,'>bgpd.conf')|| die "Can not open bgpd.conf for writing";
print BGPCONF "hostname $host\npassword $logpass\nenable password $enable\nline vty \n";
print BGPCONF "router bgp $myasn\n bgp router-id $router_id\n neighbor $remote_ip remote-as $remote_as\n";
MAXR: while ($route_count <= $max_routes ) {
$octet1=int(rand(223))+1; #generate 1st octet randomly in 1-223 range, 224 and up is multicust and class E
if ($octet1 ==127) {next;} #need to make sure that 127.X.X.0/24 is excluded $octet2=0;
while ( $octet2 <= 255 ){
$octet3=0;
while ( $octet3 <= 255 ) {
print BGPCONF " network $octet1\.$octet2\.$octet3\.0/24\n";
$octet3++;
$route_count++;
if ($route_count == $max_routes) {last MAXR;}
}
$octet2++;
}
}
close BGPCONF;
this script will generate bgpd.conf for Quagga. Since it is lab environment not connected to any real network, I do not really care about zebra configuration or restricting access to Quagga BGP console. Copy bgpd.conf file into /usr/local/etc and run /usr/local/sbin/bgpd -d -f /usr/local/etc/bgpd.conf -u root -g root Again, this is not production environment. Do not run Quagga as root in production. Here is relevant configuration from Cisco router: interface GigabitEthernet0/0 ip address 172.31.2.1 255.255.255.0 network 172.31.2.0 mask 255.255.255.0 media-type rj45 negotiation auto ! router bgp 65001 no synchronization bgp log-neighbor-changes neighbor 172.31.2.2 remote-as 65099 no auto-summary !Let's see if it works.
