Let's compare:
aggregate 144.206.0.0 mask 255.255.0.0 {
        proto direct {
                144.206.128.0 mask 255.255.255.0;
        };
};
generate default preference 190 {
        proto bgp {
                192.157.68.0 mask 255.255.255.0;
        };
};

OR

import proto bgp aspath 2895 (2587|5431) origin any preference 165      # FREEne
{

#### LEVEL 2 FILE customers/FREEnet START
# FREEnet
147.45.0.0      masklen 16      exact;
193.232.92.0    masklen 24      exact;
193.233.0.0     masklen 16      exact;
###EOF

#### LEVEL 2 FILE customers/FREEnet STOP
};

- simple, obvious.

And IOS:
! Import from FREEnet
no ip as-path access-list 6
ip as-path access-list 6 permit ^2895_(|2587|3325|5431)$
ip as-path access-list 6 deny .*
!

or, better:
no route-map mplik-in          ! mplik
route-map mplik-in permit 10
match as-path 35
set local-pref 125
set weight 50
!
!+ start mplik
!+ action clear ip b 194.58.115.26
!+ as-accl 35
!+ ip-accl 35
!
no ip as-path access-list 35
ip as-path access-list 35 permit ^3253$
ip as-path access-list 35 permit ^3253_5460$
ip as-path access-list 35 deny .*
!
no access-list 35
access-list 35 permit 193.124.176.0
access-list 35 permit 193.124.189.0
access-list 35 permit 194.58.60.0
access-list 35 permit 194.58.61.0
access-list 35 permit 194.58.99.0
...

And - ACCESS-LISTS, NUMBERS, NAMES, etc - many many noice in
the config files.

We dawmned the god when have being moved our IP routing
configuration from gated to CISCO...

Of cource gated.conf is not (in usial revision) so powerfull as IOS,
but ideas - ideas in gated was great, and gated works well even now.

For example:

% wc /etc/gated.conf
    5188   20527  160400 /etc/gated.conf
