Generic Routing Encapsulation (GRE) VPN

Merhaba, 1751 ------ 805 şeklinde olan yapıda GRE tunnel up olmasına rağmen çalışmıyor. 805 (c805-y6-mw.121-2.T.bin) üzerinde tunnel protocol GRE olarak gözükmüyor. Tunnel mode u gre/ip olarak elle set etmem de

    Merhaba,
    1751 ------ 805 şeklinde olan yapıda GRE tunnel up olmasına
    rağmen
    çalışmıyor. 805 (c805-y6-mw.121-2.T.bin) üzerinde tunnel
    protocol GRE
    olarak gözükmüyor. Tunnel mode u gre/ip olarak elle set
    etmem de
    durumu değiştirmedi. Bir IOS problemi olabilir mi?
    Benzer problem ile karşılaşan arkadaşım oldu mu?
    İyi çalışmalar.

    Kullandiginiz IOS GRE'yi desteklemiyor, IOS'u upgrade ederseniz problem
    cozulecektir.
