Need help in configuring iBGP

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
BGP router identifier 192.168.200.24, local AS number 64512
IPv4 Unicast - max multipaths: ebgp 1 ibgp 32
RIB entries 0, using 0 bytes of memory
Peers 2, using 9120 bytes of memory

Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down State/PfxRcd
192.168.200.41 4 64512 0 0 0 0 0 never Active
192.168.200.193 4 64512 0 0 0 0 0 never Active

Total number of neighbors 2

and below is the output of IP route:

vyos@vyos:~$ show ip route
Codes: K - kernel route, C - connected, S - static, R - RIP, O - OSPF,
I - ISIS, B - BGP, > - selected route, * - FIB route

S>* 0.0.0.0/0 [210/0] via 192.168.200.1, eth1
C>* 127.0.0.0/8 is directly connected, lo
C>* 192.168.200.0/24 is directly connected, 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.
Also, try to check ICMP reachable between this router and iBGP neighbor.

Hi @Dmitry,

Both the nodes are pingable from router.

vyos@vyos:~$ ping 192.168.200.41

Is there any other configuration which I am missing?

Provide show configuration commands | strip-private | match bgp
Check show log tail 300
Try to dump traffic monitor traffic interface eth1

Please find the details below:

vyos@vyos:~$ show configuration commands | strip-private | match bgp
set protocols bgp XXXXXX maximum-paths ibgp ‘32’
set protocols bgp XXXXXX neighbor xxx.xxx.200.41 remote-as ‘64512’

set protocols bgp XXXXXX parameters router-id ‘xxx.xxx.200.24’

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.
Try to increase log facility/level.

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,

I have modified the router-id. Even after that issue persists:

vyos@vyos:~$ sh ip bgp summary
BGP router identifier 192.168.200.24, local AS number 64512

Total number of neighbors 2

vyos@vyos:~$ show configuration commands | strip-private | match bgp

set protocols bgp XXXXXX neighbor xxx.xxx.200.193 remote-as ‘64512’
set protocols bgp XXXXXX parameters router-id ‘xxx.xxx.200.24’

As per my eth1 , updated the router IP

vyos@vyos:~$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

valid_lft forever preferred_lft forever
inet6 fe80::250:56ff:fe9b:f80f/64 scope link
valid_lft forever preferred_lft forever

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:
