BGP Misconception

[laxmicisco]

According to the above network , I have a network 5.5.5.0/24 in that IP is configured in R5 Loopback-0 ,And that IP is being advertised by AS 200 from R5.But when i am checking the BGP table ,The below things are showing .
in R3 , BGP table showing me that There is 2 path to reach 5.5.5.0/24 which is via R1 and R4.
in R1,BGP table showing me that There is 2 path to reach 5.5.5.0/24 which is via R2 and R3.
in R2,BGP table showing me that There is 1 path to reach 5.5.5.0/24 which is via R6 .

Why , What can be the reason ??.

Hello,

Thanks

There is no any additional configuration like route filter..Just simple IBGP
and EBGP configuration

R1 should not be advertising that subnet to R3 due to the IBGP rule. 

We need to see the configurations.
