ISAKMP Profile技術應用

ISAKMP Profile技術是IKE協商的一種新型配置方式。它主要的作用是映射我們第一階段ISAKMP參數到第

二階段IPSec隧道，可以實現一個設備和多個站點建立多個隧道。還可以很好的消除不同×××之間的影

響，讓第一階段策略和第二階段策略關聯的更加緊密。并且ISAKMP Profile普遍在EZ×××和VRF-ware 

IPSec ×××配置里邊被采用。

Site1#ping 2.2.2.2 source lo0               

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 2.2.2.2, timeout is 2 seconds:

Packet sent with a source address of 1.1.1.1 

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 104/133/148 ms
