Hi, when configuring an async port with the following two commands:
async dynamic routing
This allows the router to send and receive routing updates, correct? However, the config I am looking at also has the dialer interface which the aysnc interface uses set with the passive-interface command which should block that interface from participating in EIGRP.
So what I am wondering is if the dialer interface is in passive-interface mode then how come the async port can still send and receive routes? And if it can still send and receive routes, then how come the "show ip eigrp neighbors" command shows no neighbors?
Yes, I am saying that if the commands are enabled and the interface CAN send updates, that it will not send any updates until the routing protocol WILL generate updates. And when the interface is made passive that the EIGRP process will NOT generate any updates for that interface.
Another way of saying it is that the interface will send any updates that the routing protocol chooses to generate, but that the interface will not make up any updates on its own. Until the interface has updates generated by the routing protocol it will not transmit updates even though it CAN transmit updates.
