I'm trying to get an RB750 to join and existing (Fortigate) OSPF area. Routing is very simple in this area, all area 0, network 192.168.0.0/16 . I can see broadcasts being sent by both ends but can't form an adjacency (no neighbor on the RB750).
Config as follows;
[admin@MikroTik] /routing ospf network> print Flags: X - disabled, I - invalid # NETWORK AREA 0 192.168.0.0/16 backbone ========================================================== [admin@MikroTik] /routing ospf interface> print Flags: X - disabled, I - inactive, D - dynamic, P - passive # INTERFACE COST PRI NETWORK-TYPE AUT... AUTHENTICATIO... 0 ether1-gateway 10 1 broadcast none 1 ether2-master-local 10 1 broadcast none ========================================================== [admin@MikroTik] /routing ospf instance> print Flags: X - disabled 0 ;;; foo name="default" router-id=192.168.88.1 distribute-default=never redistribute-connected=as-type-1 redistribute-static=as-type-1 redistribute-rip=no redistribute-bgp=no redistribute-other-ospf=no metric-default=1 metric-connected=20 metric-static=20 metric-rip=20 metric-bgp=auto metric-other-ospf=auto in-filter=ospf-in out-filter=ospf-out ================== No neighbors [admin@MikroTik] /routing ospf neighbor> print
Somehow the instance-id was confused on the interface facing the rest of the system. I happened to disable ether1-gateway interface in OSPF and noticed that the new, dynamic interface was working (OSPF broadcast packets were the correct size for a system with an adjacency). I have no idea where that instance-id of 52 came from, I don't even know how to set one....
