Hi Group
As requested the config that worked for me.
Objective was/is to remove all well-known ASs and replace with one of
choice.
All routes to be on R4 with only AS 65500.
The AS of choice becomes the Confederation AS, in this case 65500.
The well-known are removed by remove statement.
R1 & 2 in AS 65100, R3 65200 and R4 in AS 10.
R1, R2 and R3 in confederation AS 65500.
R1 & R2 provide routes to be manipulated.
R1-----R2-----R3-----R4
AS 65100 65200 10
Confed AS 65500
Router R1
router bgp 65100
no synchronization
network 10.1.1.0 mask 255.255.255.0
bgp confederation identifier 65500
neighbor 10.1.1.2 remote-as 65100
no auto-summary
Router R2
router bgp 65100
no synchronization
network 10.2.2.0 mask 255.255.255.0

bgp confederation peers 65200
neighbor 10.1.1.1 remote-as 65100
neighbor 10.1.2.3 remote-as 65200
no auto-summary
Router R3
router bgp 65200
no synchronization
bgp confederation identifier 65500
bgp confederation peers 65100
neighbor 10.1.3.3 remote-as 10
neighbor 10.1.3.3 remote-as 10 remove-private-AS
neighbor 10.1.2.2 remote-as 65100
no auto-summary
Router R4
router bgp 10
