CCNA Exploration giao thức định tuyến và các khái niệm: Bảng định tuyến: Một cái nhìn chặt chẽ hơn Lab : Hiển thị IP Route Challenge Lab Bước 2: Kiểm tra đầu ra từ các bộ định tuyến R2. R2 # hiển thị mã tuyến đường ip: C - kết nối, S - static, I - IGRP, R - RIP, M - mobile, B - BGP D - EIGRP | CCNA Exploration Routing Protocols and Concepts The Routing Table A Closer Look Lab Show IP Route Challenge Lab Step 2 Examine the output from the R2 router.
