When importing a VRF with a backdoor/shamlink (as per http://wiki.mikrotik.com/wiki/Manual:OS ... g_protocol) into our management VRF, the gateways for those subnets seem to alternate between the participating routers of that VRF, before randomly settling down, most often resulting in suboptimal routing... Everything within these VRFs seem to function properly though.
Other VRFs without the backdoor/shamlink configuration import fine and work as expected.
Any ideas?
