Holding Down EIGRP Propagations
Command Meaning
passive-interface
Configuring in EIGRP prevents the interface from participating in the
routing process by preventing the sending and receiving of hello packets.
Here are the commands used in context:
Router(config)#
router eigrp 20
Router(config-router)#
passive-interface serial 0/1
Doing this will prohibit the interface from sending or receiving hello packets and, as a
result, stop it from forming adjacencies. This means it won’t send or receive route information
on this interface.
