Hi, The information you provide is a bit cryptic. For example you showed logs from r1 and r2, but the protocol names mentioned there do not correspond to the provided configs. As I understand, you want to export full view from R2 to R1, it is supposedly via protocol bgp ccre1_ipv4_1, which has export filter bgp_export. Which seems not allow ipv4 networks other than 1.1.1.184/29. The same does import filter on R1. Regards, Alexander On Sat, Feb 17, 2024 at 3:32 PM Benoit Chesneau <benoitc@enki-multimedia.eu> wrote:
So I have checked the log and I get this from the one that is supposed to received the full view:

Atter that no routes are sent. I don't really see what's wrong. R2 seems to correctly send the routes :

Is there any template I could use to send the full view to peer connected to the router directly using a vlan?

Hi,
Just to be sure. 1.1.1.1 and 1.1.1.2 are not in the single /31. Please also provide more details. What protocol output do you show? What route do you want from R2 to R1. Please look at things like these: show route all <prefix> show route all export <proto> <prefix> show route all protocol <proto> <prefix>

Hi all,
I have an issue witth the route import onbetween two machine. They are connected to each others by a vlan and at each end ana /31 is setup. I can ping between each end.
R1: VLAN330(1.1.1.1) ----> R2 : VLAN330(1.1.1.2)
R2( 1.1.1.2) is connected to upstreams transit and collect correctly the routes. But when I do the following config on this rouyer (R2):
R2 is showing some exported routes but R1 received nothing:
``` Route change stats: received rejected filtered ignored accepted Import updates: 1 0 0 0 1 Import withdraws: 0 0 --- 0 0 Export updates: 934590 27 0 --- 934563 Export withdraws: 18 --- --- --- 18 ```
What could be the issue ?
I have the following configuratiosn:
R1: ``` define AS65001_IPV4 = [ 1.1.1.184/29{29,32} ];
filter ebgp_home_as65001_import { if (net.type = NET_IP4 && ! (net ~ AS65001_IPV4)) then reject; accept; }
filter ebgp_home_as65001_export {
protocol bgp home_65001_ipv4 { local 1.1.1.2 as 209823; neighbor 1.1.1.1 as 65001; default bgp_med 0; default bgp_local_pref 400; ipv4 { import keep filtered; import filter ebgp_home_as65001_import; export all; next hop self on; }; }; ```
R2:
``` router id 1.1.1.1;
log syslog all;
log "/var/log/bird.log" all; debug protocols all;
watchdog warning 5 s; watchdog timeout 30 s;
protocol device { scan time 30; }

protocol static static4 { ipv4 { export all; }; # Reject default route route 0.0.0.0/0 unreachable;
# main route route 1.1.1.184/29 blackhole; }
filter bgp_export { if (net.type = NET_IP4 && ! (net ~ [ 1.1.1.184/29 ])) then reject;
accept; }
template bgp T_GW4 { local 1.1.1.1 as 65001; default bgp_med 0; default bgp_local_pref 400; multihop; ipv4 { import keep filtered; import all; export filter bgp_export; next hop self on; }; }
protocol bgp ccre1_ipv4_1 from T_GW4 { neighbor 1.1.1.2 as <PUBLIC AS >; }; ```
