GRE over IPSec可利用GRE和IPSec的优势,通过GRE将组播、广播和非IP报文封装成普通的IP报文,通过IPSec为封装后的IP报文提供安全地通信,进而可以提供在总部和分支之间安全地传送广播、组播的业务。 2解决方案 2.1软硬件信息 软件平台 SG6000-CloudEdge-5.5R10-v6 ...

IPSec Over GRE Tunnel Hello all! This is my first post here. I'm trying to build a GRE Tunnel with IPSec encryption (I may be phrasing this incorrectly, I realize). But this is what I'm using and I cannot for the life of me figure out why it isn't building a security association...

R1 has a GRE over IPsec tunnel to R3 which will beused to encrypt traffic between each of their LAN subnets. R1 isconnected to ‘Host’ which will be used to simulate a host on the LAN for traffic generation to test our QoS preclassify configuration. R3 is usinga loopback to simulate...
Tunnel endpoints are technically bound to IP addresses but do not need to be bound to specific devices. Any device that can strip off the outer headers and then route the inner packet can handle any GRE packet sent over the tunnel. For IPsec tunnels, the customer's router negotiates the ...
