Dear Members,
Currently I have 1 upstream router and 1 downstream Mikrotik router.
Upstream router connect to the ISP
Downstream router connect to the customer.
I am thinking to add another upstream and downstream router and use OSPF for either router or link redundancy
Router Upstream 1 (DR) and Router Upstream 2 (BDR) area 0 and area 1
Router Downstream 1 (DR) and Router Downstream 2 (BDR) area 1
Do you think this would work?
Thanks!
Might be helpful if you drew it out…but the short answer is, yes OSPF is a good protocol to use when you have multiple links. If you need traffic engineering, then BGP is the protocol you want to use.
Thank you for your reply.
My main objective is if the DR router has failed, BDR would take over as well …
I guess that would do it 
With an OSPF network type of broadcast, the BDR will take over if the DR fails, so yes that will work. As far as the way you want to position them across two areas, you would need to post a diagram to clarify your design.
Dear Ip Architect,
Thank you for your reply.
Please kindly refer to this diagram.
I am planning to add 2 OSPF router per area as listed on this diagram.
May i have your opinion please

The diagram looks like a config that would work but whether it is the best choice really depends on several factors which are not stated. e.g. the nature of those links is unclear.
Dear Celtic,
The links are fiber optic.
I have two questions on the OSPF router on each area …
on the main distribution OSPF router I have configured it Redistribute Default route always as type 1 and I can see 0.0.0.0/0 is being pushed to the Area OSPF routers.
From the OSPF routers to the customer do i need to set anything if i gave a subnet say /29 to them?
Thanks!
