em đọc trong tài liệu thấy nó nói cái khái niệm Administrative Distance như thế này :
The administrative distance is an optional parameter that gives a measure of the reliability of the route. A lower value for the administrative distance indicates the more reliable route. Thus, a route with a lower administrative distance will be installed before an identical route with a higher administrative distance. The default administrative distance when using next-hop address is 1, while the default administrative distance when using the outgoing interface is 0. If an administrative distance other than the default is desired, a value between 0 and 255 is entered after the next-hop or outgoing interface as follows:
waycross(config)#ip route 172.16.3.0 255.255.255.0 172.16.4.1 130
bác nào giải thích cho em với
cảm ơn bác nha
