CloudEOS and vEOS Router Configuration
Use this procedure to configure GRE-over-IPsec tunnels on a CloudEOS and vEOS Router instance. Once the procedure is complete, configure the other tunnel end-point on the third party peer router.
Note:The CloudEOS and vEOS Router by default uses IKE version 2 for all IPsec
tunnels. If you want to configure a GRE-over-IPsec tunnel that uses IKE version
1, explicitly configure the CloudEOS and vEOS Router to use IKE version 1.
Procedure
Complete the following steps to configure the CloudEOS and vEOS Router instance to share a GRE-over IPsec tunnel.
To use IKE version 1, complete the section below, then continue with
the following steps. To use the default version IKE version 2, begin with Step
1 below.
switch(config)#ip security
switch(config-ipsec)#ike policy ike-peerRtr
switch(config-ipsec-ike)#version 1
