But if tunnel is ipsec ipv4 on Cisco, then it is supported. However, I don't quite sure how it is implemented in Huawei (the another side). There is need to verify that huawei side sends OSPF hello. On Cisco side (ISR) you may enable debug ip ospf hello ; debug ip ospf a...
•Simplifies management---Customers can use the Cisco IOS®Software virtual tunnel constructs to configure an IPSec virtual tunnel interface, thus simplifying VPN configuration complexity, which translates into reduced costs because the need for local IT support is minimized. In addition, existing man...
I am getting alarm Tunnel0 protocol "DOWN" interface periodically. When i checked "Show ip int br" in Cisco ASR920, Tunnel0 interface showing status “up” and protocol “down”, how we can make this protocol “up”. Could any one
如果是使用TUNNEL起VPN的话,不管哪个运营商应该都没有问题,能起来,但是如果走IPSEC的话,请和运营商联系,运营商需要支持你做IPSEC。另外,如果本地的VPN设备与对端之间有NAT,建议把NAT改为静态的NAT,由于动态NAT改变端口,端口一旦发生变化,VPN无法配对。
用GNS3做
