Some comments on this draft:
1. The size of network is increasing, but it is becoming more flat. Is it the
right direction to make the network more hierarchical?
2. More hierarchical network means the traffic will also be traversed in
hierarchical way, is it more efficient?
3. Is there any ot
Speaking as LSR WG Member:
Hi Aijun,
I agree that most deployments will not move to greater than two levels given
that we’ve gone this many decades with two and the predominant underlay
deployment is one level. However, there appears to be sufficient interest and
couple with good technical work

Well, given that we’re talking a link state protocol running SPF over a
database in O(n log n) time, it’s pretty clear that we don’t want to scal
Hi Tony,

Since Aijun posted his question I was trying to think of such model, but
failed.
While it is easy to envision this with DV protocols say BGP - do you have
any pointer to a

Hi, Acee:
It’s interesting to extend the ISIS hierarchical in this way. What I
considering is the complexity of its deployment in future. Maybe we can
discuss/emphasizes on this aspect deep later.
Best Regards.

Hi, Tony:
Would you like to elaborate this in more detail to show how you design the
control plane hierarchically but the traffic can be transported horizontally?
Let’s consider the following graph:
If, as you stated, we connect R1 and R7 via one link(although we will not do
so, if we
