Doubt about Bgp

[Prech]

Hi , i have to connect three routers in the same bgp "as" to another router in another bgp "as" but, when i run show ip bgp summary the connection from one router appears as down to the neighbor in a different "as".

This is my config for the routers:

router 1:

en
config t
interface loopback 1
ip address 10.1.1.1 255.255.255.0
exit

interface gigabitEthernet 0/0
ip address 10.1.103.1 255.255.255.248
no shutdown
exit
interface gigabitEthernet 0/1
ip address 10.1.102.1 255.255.255.248
no shutdown
exit
interface gigabitEthernet 0/2
ip address 192.168.14.1 255.255.255.252
no shutdown
exit

router ospf 1
network 10.1.1.0 0.0.0.255 area 0
network 10.1.103.0 0.0.0.7 area 0
network 10.1.102.0 0.0.0.7 area 0
network 192.168.14.0 0.0.0.3 area 0
passive-interface Gi0/2
exit

interface loopback 1
ip ospf network point-to-point
exit

router bgp 65500
neighbor 192.168.14.2 remote-as 64600
neighbor 10.2.2.2 remote-as 65500
neighbor 10.2.2.2 update-source loopback1
neighbor 10.3.3.3 remote-as 65500
neighbor 10.3.3.3 update-source loopback1
network 10.1.1.0 mask 255.255.255.0
exit

 router 4:

en

ip route 172.16.0.0 255.255.240.0 null0
router bgp 64600
neighbor 192.16.34.1 remote-as 65500
neighbor 192.16.14.1 remote-as 65500
network 172.16.0.0 mask 255.255.252.0

network 172.16.8.0 mask 255.255.252.0
network 172.16.12.0 mask 255.255.252.0
network 172.16.0.0 mask 255.255.240.0
exit

Can someone tell me what i'm doing wrong. Thanks

Hello,

it looks like on Router 4, you have a typo in the IP address:

--> neighbor 192.16.14.1 remote-as 65500

needs to be:

neighbor 192.168.14.1 remote-as 65500

Thank you for the answer! It was a stupid mistake. Now in a different topic , do you know how can I config the router so that the prefered path from the router 4 to the AS 65500 is through the router 1? Thank you once again.
