Generic Routing Encapsulation (GRE) VPN

[Engin ZEREN]

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.
