OSPF Loopback issue

RouterOS Forwarding Protocols
1

Hi Guys,

I have kind of issue with my loopback inteface on my routers, I have enable VPLS/BGP/MPLS/OSPF and i having flapping on some services, and i find packet loss to my loopbacks :frowning: :frowning: :frowning: .
I can ping through Links and no packets lost, but if i do ping to loopbacks i got packets lost…
Any advise ???

Here an example:
MK-CCR1036-12G-4S
