I strongly support the adoption of the IS-IS TTZ draft.
For the large scale network, if we just run the IS-IS in a large area, the LSDB will be very large.
In addition, the convergence time will last for a long time. But TTZ is a good way to reduce the network size and the number of the Link state can be reduced largely.

BR,
Rouxin

I support adoption of the IS-IS TTZ draft.
It is very useful for the large network with abstracting a zone to a single virtual node.
The size of the LSDB can be reduced dramatically.

best,
Reta
