distinguish different incoming SAs and you can select between different encryption algorithms,
authentication algorithms and key groups when you configure a VPN rule. The ID type and content
act as an extra level of identification for incoming SAs.
The type of ID can be a domain name, an IP address or an e-mail address. The content is the IP
address, domain name, or e-mail address.
13.3.7.1 ID Type and Content Examples
Two IPSec routers must have matching ID type and content configuration in order to set up a VPN
tunnel.
The two LTE Devices in this example can complete negotiation and establish a VPN tunnel.
The two LTE Devices in this example cannot complete their negotiation because LTE Device B’s
Local ID type is IP, but LTE Device A’s Remote ID type is set to E-mail. An “ID mismatched”
message displays in the IPSEC LOG.
13.3.8 Pre-Shared Key
A pre-shared key identifies a communicating party during a phase 1 IKE negotiation (see Section
13.3.3 on page 94 for more on IKE phases). It is called “pre-shared” because you have to share it
with another party before you can communicate with them over a secure connection.
Table 41 Local ID Type and Content Fields
LOCAL ID TYPE= CONTENT=
IP Type the IP address of your computer.
DNS Type a domain name (up to 31 characters) by which to identify this LTE Device.
E-mail Type an e-mail address (up to 31 characters) by which to identify this LTE
Device.
The domain name or e-mail address that you use in the Local ID Content field
is used for identification purposes only and does not need to be a real domain
name or e-mail address.
