I am *supposing* bug with rp_filter=loose option.
From time to time, I am loosing connectivity with one of peering partners.
Thats not L2 problem, I can refresh, resend routes, i see established session and everything seems to be OK.
However, i don't see RX traffic on that interface (besides of bgp packets). Re-enabling interface, peering route - nothing helps. Only reboot.
Does rpfilter silently drops RX packets ? I suppose that bcs of some bug it may start to drop all incoming routed traffic on that interface.
Is there anyway to debug it ? Does rpfilter have some counters avaiable from mikrotik level, or it will just seen as Rx drops ?
