Forming Adjacencies

[otto4u]

Yh! I was looking for an example actually! and you gave one! thanks buddy!

But still even in medium-to-large companies, you won't find more then 10 or so routers(and again, assuming one router for each branch)! but as you said, Its(Switch-as-a-center) worth if we need more than one router in a branch, but again, Isn't this is a bit uncommon? I mean they can opt for something like VLANs!(segmenting their branch-network for each department!).

And one more question is raised! We don't necessary need BD/BDR election-option in our network right?(from this I mean, for small or medium enterprise), so the use of DR/BDR elections comes into play on something exceptionally odd(as you mentioned, for ISPs), and its not the norm, right?

Buying routers is expensive and not many companies would buy more than one for there entire branch! so OSPF is basically for very large or a bit odd networks(connecting more than one router for a branch), do you agree?

It would be nice to have your opinion!
