After some long talks and thinking, I am going to start over with everything. I have 3 8320s I am going to use as my Core (I am going to with OSPF).
I am going to configure it all and test it first before I deploy it, I currently have them configured just running OSPFv2. My Main switch (switch A) can ping both switch B and C. Switch C can ping Switch A (both IP addresses I am using, but not Switch B. Switch B can ping one IP on Switch A, but not the second or Switch C. Below are my configs ( I am sure it is something simple I am missing)...
Switch B <--> Switch A <--> Switch C

Ok, give me a little bit and I will get one put together and post it.

Hi, simple question: how many Routers are running in your internal network? if just one (your Layer 3 Switch acting as your "Core" for your internal VLANs) then the question is: why OSPF should be used at all?
A network diagram of what you have and a network diagram of what you want (topologically speaking) would be of help to help your understand how and where you can move.

Hello,
I know i need to add more info, but i am inherenting a few networks. They were built about 20 yrs ago and then all kinds of network gear was thrown on it. I had no diagrams or anything when i started, i think i have a good one now and a good idea of what im getting into…
we are running ospf. We have it configured on an HPE 5900. I am much more familiar with Cisco and working in Aruba, but there is no other switch in the entire network with any kind of ospf config on it. From what i have been reading and from cisco, there should be router IDs and such?
Also, the HPE 5900 is the main switch and thats where our backbone starts. The plan was to use a /29 subnet when they installed this equipment which gives a range of 6 IPs and they are trying to use them for the backbone switches (that was what they planned, not what happened) and another subnet for the switches coming off the backbone.
Im trying to figure out where to start here. I have my diagram so i have a good idea of whats out there, but im not very familiar with Aruba routing yet. From what i know and read, i need to configure OSPF on other switches not just the main one right? There are lots of switches that are up and running, but i cannot ping or putty into them, i can only telnet from other switches… I think getting uplinks set up properly first is where i should start, but any help or suggestions would be great
on a side note, i do have some cx series switches i am going to use to replace a chassis switch that is failing then i want to make the cx switches the main switch and branch out from there. So maybe i should just give up with what i am trying to do now and focus on reconfiguring all the routing? I kind of want to get things working properly first in case i need to get and replace anything else…
