Hi Team,
I have deployed VyOS (1.1.8) over vSphere VM successfully. I am trying to use the iBGP protocol. I have done the below settings but still, the BGP connections are not in the established state. I am still learning so can you help me in the configuration part.
vyos@vyos:~$ sh ip bgp summary
Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down State/PfxRcd
Total number of neighbors 2
and below is the output of IP route:
vyos@vyos:~$ show ip route
S>* 0.0.0.0/0 [210/0] via 192.168.200.1, eth1

Hello @harshit , 1.1.8 is EOL, I recommend you update the router to the latest rolling or to stable 1.2.x version.

Hi @Dmitry ,
Both the nodes are pingable from router.

Is there any other configuration which I am missing?

Please find the details below:
vyos@vyos:~$ show configuration commands | strip-private | match bgp
Logs:
vyos@vyos:~$ date;show log tail 300#1 SMP Sat Nov 11 12:10:30 CET 2017OSI(Linux) query ignored ] (20131115/hwxface-580)
This cli is not present in 1.1.8 version:
vyos@vyos:~$ monitor traffic interface eth1
Invalid command: monitor [traffic]
Also, I have one more query, What is the router-id? Is it we can give any random IP to it when configuring BGP?

Roiter-ID - an address that presents one of the interfaces.
Router id
vyos@vyos:~$ sh ip bgp summary
BGP router identifier 192.168.200.1, local AS number 64512
But in configuration.
set protocols bgp XXXXXX parameters router-id ‘xxx.xxx.200.24’
Try to delete this line,

Viacheslav:
sh ip bgp summary
I have modified the router-id. Even after that issue persists:
vyos@vyos:~$ sh ip bgp summary
Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down State/PfxRcd
Total number of neighbors 2
vyos@vyos:~$ show configuration commands | strip-private | match bgp
As per my eth1 , updated the router IP
vyos@vyos:~$ ip a

I have also increased the log level using below command.
vyos@vyos# set system syslog global facility all level
Please let me know if i have to do some more steps?

set system syslog global facility all level all
And try reconfigure bgp
delete protocols bgp
commit
Then apply config again (with real data)
set protocols bgp XXXXXX neighbor xxx.xxx.200.41 remote-as ‘64512’
set protocols bgp XXXXXX neighbor xxx.xxx.200.193 remote-as ‘64512’
commit
And then check logs
show log tail 300

I have executed it again as suggested by you. Please find the logs:
Sep 3 07:15:50 vyos getty[9879]: ttyS0: tcgetattr: Input/output error#9910 failed with exit status 1)#10485 failed with exit status 1)
Also, when I check the neighbors, it gives below o/p.
vyos@vyos:~$ show ip bgp neighbors
For address family: IPv4 Unicast
Connections established 0; dropped 0
BGP neighbor is 192.168.200.193, remote AS 64512, local AS 64512, internal link
For address family: IPv4 Unicast
Connections established 0; dropped 0
