  1. Hi Rene,

    Is there a tutorial on EIGRP default routes using redistribution?

    Cheers

  2. Hi Shashank,

    The 192.168.23.0 /24 network is used as the default network which means R1 will send packets with an unknown destination there. However, R2 still has to know where to forward packets to…it has no clue how to reach 3.3.3.0 /24 so that’s why we need the default route.

  4. Hi @wilder7bc,

    The ip default-network command is one of the weirder commands out there. I think I originally tried it on 12.4 when I wrote the lesson. On IOS 15.x, I can’t make it work…

    The funny thing is, when I load my config, R1 doesn’t see 192.168.23.0/24 as a default network:

    R1#show ip route 
    
    D     192.168.23.0/24 [90/3072] via 192.168.12.2, 00:03:30, GigabitEthernet0/1
    

    Once I remove and re-add the network command on R2, it does get propagated to R1:

    R2(config-router)#router eigrp 12
    R2(config-router)#no network 192.168.23.0
    R2(config-router)#network 19

  5. Hello Minghui

    When you use an Ethernet port as an exit interface, what will happen depends on several factors including the IOS version and the platform that you are using. In some platforms/IOS combinations, what Rene has implemented will work as configured. However, there are some other situations in which it doesn’t. The following link shows a couple of examples where you have an IP address as a next hop IP or an interface as an exit interface. In this example, the use of an exit interface fails.
