There is an article i read somewhere discouraging engrs not to do redistribution of connected routes (except on few occasions) .in an isp environment were you have many sub-component IPs in a router . it becomes difficult to be adding each network or summary address on ospf network in order to advertise it . These is were mikrotik os v 7 beats alot of other vendor routers . all you need do, to advertise the sub-component IPs,is to select all (all as in interface under interface-template) ,under the ospf proccess . Select all( (all as in interface under interface-template) and make it passive ,while enabling only the ospf interface to be active . in these light all sub-component will be advertise automatically and seen in other routers as LSA type 3 (inter-area) instead of redistribution connected routes (LSA type 4 and 5) .i say kudus to mikrotik for these feature in os 7 .

Great literally having the ospf issue link down

Very interesting. Thank you!

<a href="#" class="seekto" data-time="138">2:18</a> this is very informative but i have personally never seen anything like this happen. maybe this happened in previous RouterOS versions? we run OSPF in bridge interfaces (which means the interface never goes down) as default OSPF type and never seen OSPF get stuck when the link comes back up.

so you lose a leg if your ospf network does run well in toscany? lol
