    192.168.4.26 is a class C address, you are using an illegal /16 mask, Ripv2 doesnt support
    masks shorter then the natural mask.
    Networking, sometimes i love it, mostly i hate it.Its all about the $$$$

    You have misconfigured the second network statement. Type network 192.168.4.0 instead.

    I thought RipV2 was classless (one of it's biggest improvements over v1)?
    We responded to the Year 2000 issue with "Y2K" solutions...isn't this the kind of thinking that got us into trouble in the first place?

    RIP v2 is classless, and will advertise a route regardless of the mask and class in use. The problem here is not related to the advertisement, but the network address in use. The problem is RIP expects a network address in the "network" command specified under the routing process. This allows advertisements to be sent on any interface matching the network address or a subnet of the network address, but not a supernet address, which is being used in this example.

    Adding a secondary address with a network address or a subnet address of the classful network will allow rip to send updates onthe interface, but it will source them from the primary address of the interface.
    The only easy day was yesterday!

    Ah, thanks. So essentially it's support for classless is hobbled in a way, yes it advertises classless subnets but it won't accept the entirety of class range as one subnet from the Network command even if that's desired.
