Hi All,
Just want to clarify something regarding EIGRP interface-passive command. I made serial0/0 passive in eigrp, but i can still routes passing to the serial link. Do i need to make the serial sub-interface passive rather than the serial interface to stop inbound and outbound advertisements?
Here are my current configs.
interface Serial0/0
description Serial0/0
bandwidth 64
no ip address
no ip redirects
encapsulation frame-relay
no ip route-cache
no ip mroute-cache
no fair-queue
service-module t1 timeslots 1
frame-relay lmi-type ansi
!
interface Serial0/0.300 point-to-point
description PVC TO Remote
bandwidth 32
ip address 10.209.22.153 255.255.255.252
ip accounting output-packets
ip nat outside
no ip route-cache
no ip mroute-cache
frame-relay interface-dlci 300
frame-relay payload-compression packet-by-packet
!
interface Serial0/0.400 point-to-point

Yes,
The passive interface command would be required under the sub-interface.It need to reference the interface carrying the IP address
However it would prevent the formation of neighbor adjacency. If you just want to restrict routing updates, the distribute-list you configured is the correct way
