TSHOOT 300-135 Ticket #14

TSHOOT Ticket #14 on EIGRP Passive Interface

Hi ! everyone on today we are going to learn about EIGRP passive interface which is done in packet tracer version 7.1 with the topology given below.

The neighborship between R4 and DSW1 wasn’t established. Client 1 can’t ping R4

Configuration on R4:

router eigrp 10
  passive-interface default
  redistribute ospf 1 route-map OSPF->EIGRP
  network 10.1.4.4 0.0.0.3
  network 10.1.4.8 0.0.0.3
  network 10.1.21.128 0.0.0.3
  default-metric 10000 100 255 1 10000
  no auto-summary

Answer 1: R4
Answer 2: IPv4 EIGRP Routing
Answer 3:  enter no passive interface for interfaces connected to DSW1 under EIGRP process (or in Interface f0/1 and f0/0, something like this)

Note: There is a loopback interface on this device which has an IP address of 10.1.21.129 so we have to include the “network 10.1.21.128 0.0.0.3” command.

* Just for your information, in fact Clients 1 & 2 in this ticket CANNOT receive IP addresses from DHCP Server because DSW1 cannot reach 10.1.21.129 (an loopback interface on R4) because of the “passive-interface default” command. But in the exam you will see that Clients 1 & 2 can still get their IP addresses! It is a bug in the exam.
