Name
passive-interface — router
Synopsis
passive-interfaceinterface
no passive-interfaceinterface
Configures
Disables a routing protocol on a specific interface either partially (RIP, IGRP) or completely (EIGRP, OSPF, etc.)
Default
None
Description
For RIP and IGRP, this command causes the specified
interface
to listen for routing updates
but prevents it from sending them. For OSPF, EIGRP, or other
“hello-based” routing protocols, this command effectively
disables the protocol on that interface (both sending and receiving).
These protocols cannot operate without exchanging hello messages.
Example
router igrp 100 network 10.0.0.0 ! Suppress routing advertisements on serial 1 passive-interface serial 1
