Hello,
i want to route my subnet ip with as number in mikrotik os. Datacenter say me we must run BGP and give me datacenter router ip and as number.
at first i go to routing → BGP ->instances
and add new with ‘BGP’ name and my AS and mikrotik ip address as router id.
then add new peers with instance ‘BGP’
remote address = (datacenter router id)
remote as = (datacenter as)
nexthop choice = default
multihop ticked
holdtime 3
ttl 5
default originate never
in advanced
address families : ip ticked
update source none
cisco vpls nlir length format: auto bits
and in network tab i add new with my ip format like this : 79.23.35.15/24
in a log file i see :
failed to open tcp connection: connection refused
remote address= (datacenter router id)
can you help me for this issue?
In your peer, ‘Advanced’ tab, set ‘Update Source’ to the IP address datacenter setup as your BGP peer. seems like your BGP connection is being established from the wrong address
also, check firewall filter rules in input and output chains
thanks for your replay Chupaka
i dont have any firewall filter rules in mikrotik.
i edit Update Source , but now i faced problem.

problem solved. datacenter router make this problem.
This meas TCP port 179 for BGP is not answering on the remote end which can be one of several things
- The source of your peering
- Firewall rules
- Issue with the router you are peering with.
