dead-interval (time; default: 40s) - specifies the interval after which a neighbor is declared as dead. The interval is advertised in the router's hello packets. This value must be the same for all routers and access servers on a specific network
hello-interval (time; default: 10s) - the interval between hello packets that the router sends on the interface. The smaller the hello-interval, the faster topological changes will be detected, but more routing traffic will ensue. This value must be the same on each end of the adjancency otherwise the adjacency will not form
You can use any subnet between your p2p links and the router - but choose a subnet that is only as big as necessary. So if you have used a /30 on the wireless interface of your p2p link and the p2p device is the only one connected to the router port then use another /30 between its ethernet interface and the router.Hello,
I'm continuing my testing on OSPF and I have a new question for you!
May you help me to understand what is a good ip plan?
I read "Burning Bridges" here:
http://www.mywisptraining.com/wp-conten ... Routed.pdf
I understand I have to remove switches and add router in place, but... What address should I assign to each port of the router?
I mean: for P2P links I use a /30, but what about the router?
In the example I posted on the first post, what IPs should I assign to the last RB750 and the NetMetal?
Thank you for helping me to understand
Excellent point on not flooding a bunch of LSAs.For AP's it is best to avoid using OSPF to publish client facing subnets actively. As clients connect and drop it creates new LSA's across the whole network so better to not specify the client device subnet in /route ospf net and better to set the /rou ospf instance to publish connected instead. This way the AP's subnet gets published as a whole and not on a per client address basis.
If you have an ethernet interface on your Mikrotik bridged via 3rd party wireless link (e.G SAF etc) then you will most likely need a /29 which will give 8 IP Adresses less 2 (broadcast and network) so 6 usable addresses. 1 for each Mikrotik and 1 each for your radios. As the radios may not support OSPF set their Gateway to point to the Mikrotik nearest where you are connecting from.
Network type=Broadcast should be OK if the link is a true L2 bridge but if you experience difficulty or instability then try setting the relevant interfaces to network-type=point to point
