      Tunnel ne icin kullaniliyor burda?
      RPF, load sharing?

      Tünel interface'inin kullanılma amacı multicast datanın iletilmesidir. Üyedeki Cisco router ile İMKB merkezi arasındaki Cisco router arasında multicast protokollerini desteklemeyen cihazlar bulunduğu için tünel kullanmak durumunda kaldık.

      sh ver nedir?

      Programlar kapalı olduğu için olması gereken mcast route bilgisi bu kayıttta yok.

      source ve group adresi nedir?

      Olması gereken route (172.1.1.3, 233.127.255.1)
      Bu ikisi zaten source,grup tanımı.

      Bu arada mcast ilem ilgili olarak RPF check konusunda bir problem yok çünkü statik olarak multicast route'ları tünel olarak gösterilmiş durumda.

      Umarım bilgiler yardımcı olur.

        Arkadaşlar merhaba,
        Cisco 2621 XM router'u IMKB'ye bağladık. LAN portuna bağlı olan bir PC'ye multicast trafiği geliyor.
        Yayın multicast yayını merkezden kesiliyor.
        Sabahları router restart edilmeden veri gelmiyor. "Show run" çıktısı aşağıdadır.
        Bu problemin sebebi ne olabilir?
        Yardımcı olabilecek arkadaşlara şimdiden teşekkürler.

        Yasin BATMAZ.
