Hi.
Something like:
template bgp bgp_local {
local as my_as;
import filter import_bgp;
export filter export_bgp;
multihop;
rr client;
rr cluster id 1.0.0.1;
}
# R2 - also RR; import all routes from it
protocol bgp bgp_peer_r2 from bgp_local {
description "R2";
neighbor x.x.x.x as my_as;
import all;
}
# C1 - client
protocol bgp bgp_peer_c1 from bgp_local {
description "C1";
neighbor x.x.x.y as my_as;
}
cluster id should be same on all RRs.

Hi Andrew,
As I am new to Bird I can not find a good example how to create a RR
cluster with two routers R1 + R2.
Do you have experience with a RR cluster with multiple routers? My
biggest question is acquily how to config the
sessions between R1 + R2 as clustermembers without creating a loop.

You may redistribute all routes between R1 and R2 using RR (both
received from R3 and received from uplinks), and redistribute just
default to R3 using separate table (with static default and routes
peering to main table).

Hi Adrew,
I thought about this option, I don’t want to pass a full BGP table
towards R3.
In other words R1 + R2 should be used for routing for all routes
and R3 should only
route net A and net B and must route through to reach other networks.

Hi.
You should configure R1 and R2 as route reflectors.

I am trying to achieve a redundant routing setup with two
routers with the same ASN who do prefix delegation to a lower

The setup is the following:
AS1000 ISP1 ISP2 AS2000
| |
| |
AS10000 R1 ======== R2 AS10000
prefix /22 \ iBGP / prefix /22
\ /
\ /
\ /
R3 AS65000
/ \
/ \
net A net B
prefix /24 prefix /24
Does anybody has experience with this kind of setup?
