2008-02-23 04:53:28来源：互联网 阅读 ()
--------------------------------------------------------------------------------R1 (s0/0) -------------------R3 --------------------(s0/0) R4
1. R3 is Hub
2. R3 can use point-to-multipoint subinterface
3. R1 and R4 used physical interface only
4. only between R1 and R3 can use MD5 authenticaiton
