Hi all,
I have the following topology:
A --54/54-- B --54/54-- C --2/2-- D --55/55-- E --55/55-- A
where A, B, C, D, E are MikroTik devices of verious versions 2.9.x.
Node A has been included intentionally twice indicating that the topology is a closed loop. The "x/y" notation indicates that the OSPF cost for node X to Y is x while the cost from node Y to X is y.
My aim is to achieve load balancing between nodes A and D while still keeping dynamic routing (OSPF).
As can be seen the total OSPF cost for both available routing paths between nodes A and D is 110/110. Consequently, one would expect to observe in the route lists of nodes A and D a dual gateway to either of both nodes, i.e.:
1. A to D via B, E .
2. D to A via C, E
Node D (MTv2.9.2) manages to maintain dual gateways to A as described above while node A (MTv2.9.14) maintains dual gateways only for approximatelly 15min and after that sticks to B.
Why is node A giving up gateway E?
This is a list of all the MT versions running on each machine:
1. A MTv2.9.14
2. B MTv2.9.14
3. C MTv2.9.6
4. D MTv2.9.2
5. E MTv2.9.11
Thanks in advance
