| | رد: هل يمكن عمل PING عند اختلاف الـ IP للمنافذ الـ Serial
If the interfaces are in different subnets, it will show an up/up state but still not be functioning. This is for HDLC.
For PPP links, with an IP address/mask misconfiguration, both routers’ interfaces also are in an up/up state, but the ping to the other routers’ IP address actually works. This is because a router using PPP advertises its serial interface IP address to the other router, with a /32 prefix, which is a route to reach just that one host. So both routers have a route with which to route packets to the other end of the link, even though two routers on opposite ends of a serial link have mismatched their IP addresses.الموضوع الأصلى من هنا: منتديات سيسكو التعليمية | كن بين الخبراء ! http://www.ciscovb.com/vb/2598-post17513.html
A route with a /32 prefix, representing a single host, is called a host route
