Failed peering BGP Mikrotik 2.9.50 with Cisco Router 7602

RouterOS General
1

Dear folks,
I have run BGP peer between MT 2.9.27 and Cisco 7602, everythings run well. Then we have bought a MT 2.9.50 level 6 license and 4 port gigabit pci interface (44G). I don’t modify the configuration on 7602. And I export the MT 2.9.27 configuration. The BGP section from exported configuration (with ip-7602 and our_network stripped) is:

/ routing bgp
set enabled=yes as=64515 router-id=0.0.0.0 redistribute-static=no
redistribute-connected=yes redistribute-rip=no redistribute-ospf=no
/ routing bgp peer
add remote-address=[ip-7602] remote-as=65015 route-reflect=no
multihop=yes prefix-list-in=“” prefix-list-out=“”
/ routing bgp network
add network=[our_network/prefix]

And then I copy the BGP configuration to MT 2.9.50, but BGP peering won’t work.

I notice the peering status (from winbox) interchanged from connected to not-connected (vice-versa) within 10 - 15 seconds.
I also check the cable connection between MT and 7602 and the physical connection is OK.

Is there any misconfiguration with my MT? Or there is a new command for MT 2.9.50 regarding the BGP?

Thank you for your help.

I am upgrade the routerOS 2.9.50 to routerOS 3rc13, after rebooting the MT, fortunately the BGP back to work again. So problem solved. But, IMHO this is not the right way to solved this problem. If anybody sincere to share their experience regarding this, it would be helpful.

have you tried routeting-test package with 2.9.50?

As long as I remember, I didn’t try the routing-test package in 2.9.50, only the routing package. Is there any changes for this package between 2.9.27 and 2.9.50? Unfortunately, I couldn’t downgrade the current MT router, because this router is in production state for my network.
