RouterOS v6 to v7 update broke my BGP peering

Wed Dec 15, 2021 10:01 am

Hi there.
I've setup BGP in RouterOS v6 like this:
/routing bgp instance set default as=64999 ignore-as-path-len=yes router-id=10.9.0.10/32
/routing bgp peer add hold-time=4m in-filter=bgp_in keepalive-time=1m multihop=yes name=antifilter remote-address=10.9.0.1/32 remote-as=64998 ttl=default 
/routing filter add action=accept chain=bgp_in comment="Set nexthop to VPN" set-in-nexthop-direct=*12
When I updated to RouterOS v7 it broke and I can't really see any status messages nor new routes on my MikroTik.

Current config is:
/routing bgp template
set default as=64999 disabled=yes input.ignore-as-path-len=yes name=default output.filter-chain=dynamic-in .network=bgp-networks .no-client-to-client-reflection=yes router-id=\
    172.30.1.2
add as=64999 disabled=no input.ignore-as-path-len=yes name=my output.network=bgp-networks router-id=10.9.0.10 routing-table=main
/routing ospf instance
add name=default-v2
/routing ospf area
add disabled=yes instance=default-v2 name=backbone-v2
/routing table
add fib name=HTTP
add fib name=DNS
add fib name=DNS-Router
/routing bgp connection
add cisco-vpls-nlri-len-fmt=auto-bits connect=yes disabled=yes hold-time=4m input.filter=bgp_in keepalive-time=600ms listen=yes local.role=ebgp multihop=yes name=antifilter \
    remote.address=163.172.210.8 .as=65432 .port=179 routing-table=main templates=default
add as=64999 cisco-vpls-nlri-len-fmt=auto-bits connect=yes disabled=no hold-time=4m input.filter=bgp_in .ignore-as-path-len=yes listen=yes local.role=ebgp multihop=yes name=VPS \
    output.network=bgp-networks remote.address=10.9.0.1/32 .as=64998 .port=179 router-id=10.9.0.10 routing-table=main templates=my
/routing filter rule
add chain=bgp_in comment="Set nexthop" disabled=no rule="if (protocol bgp) { set gw-interface *12; accept; }"
Can someone please help me to restore BGP?

I'm constantly getting this error as well:
Connection closedBgpInput{ sk=Socket{ 3[
Not sure where to dig for better logs. Can someone please point me towards manual?

Make sure you have correct local.address set.

On the Connection Tab, make sure to assign the local address. I had this same issue and that was the solution.

It is set right. BGP Sessions are unstable. Every 3/4 hours getting Hold time expired or EBGP peer is not on a shared network and multihop is not configuredBPS ...
What could be the cause?

Mikrotik said when I emailed

"Thank you for the report, it is a known problem and will be fixed in the future."
