Mong duoc giai thich ro hon!
Trong ICND co viet la:
" Classless routing protocols transmit the subnet mask along with each route in the routing updates sent by that protocol. Classfull routing protocols do not transmit mask information. So, only classfull routing protocols support VLSM. To say that a routing protocol is classless is to say that it supports VLSM, and vice versa"
Mình nghĩ là có sự nhầm lẫn chăng??????? Classfull routing protocols (phần in đậm) nên được thay bằng classless routing protocols
Mong được các bạn chỉ giúp!
