    OSPF summarization on ABRs and ASBRs and not on other OSPF routers

    KayouMT-NET

      Hi,

       

      After long time "googling", I found a link a potentially understandable link on the reasons why OSPF summarization is allowed only on ABR and ASBR : http://smitley.net/?p=205.

       

      I'm looking for a lab showing (step-by-step) what would be the impact of doing summarization on internal router, instead of doing it on ABR or ASBR.

       

      Thanks in advance for any help !
