Is the Debian router at the other end logging anything weird on its end? What happens if you advertise as 4x /24's instead of the single /22? Any chance of getting a packet logger somewhere in the chain so you can see exactly what the two routers are saying to each other? -----Original Message----- From: Public [mailto:public-bounces@talk.mikrotik.com.au] On Behalf Of Damien Gardner Jnr Sent: Friday, 27 March 2015 1:39 PM To: MikroTik Australia Public List Subject: Re: [MT-AU Public] RouterOS rebooting over and over? Possibly BGP + ipipv6 tunnels? Yeah, iBGP Remote router is debian with quagga purely passing on the advertisements it receives (with the appropriate filters incase I fubar something at this end ;) ). Disabling the accept input filter didn't help. Disabling the output filter did help, but I already knew that - sending another prefix works fine also.. turning off multihop didn't fix it either :( Thanks, Damien
