OSPF between 5400

[YenLin]

Hi all,

Our current network is based on 1 5400 core switch to do Layer 3 routing.(intervlan)

I am designing to use ospf as their routing protocol as attached picture.

Their vlan 1906 and loopback 0 act as their backbone area and their sub area is 2040, which is 10.128.0.0, 10.131.0.0, 10.136.0.0, 10.137.0.0, 10.138.0.0 and 10.139.0.0.

The problem is how should it config for Node3, GBRYC, LongPav and Newpowerhouse to enable ospf routing protocol.

The furture design will allow them to be able to support ECMP.(Each cost multiple path).

We will create mutiple link to accomplish partial mesh topology.

For example, there are some fiber connected between Reefview to Node3,Node4 to Node3 and so on.

Any recommandation would be appreciated.

Hi YenLin,

With the number of switches in your topology, i would not use multiple OSPF areas. With that number of switches, there's no need to complicate it with multiple areas and summarisation.
