Adding Layer 3 IP Policies

Table 48 Hub and spoke policy entries (continued)

Field

Description

IPSec

Specifies the encryption and authentication algorithms used in an IPSec policy.

 

Select the encryption algorithm from the Encryption Algorithms list:

 

• AES - Advanced Encryption Standard (default)

 

• 3DES - a more secure variant of Data Encryption Standard

 

Select the authentication algorithm from the Authentication Algorithms list:

 

HMAC-SHA-1- Secure Hash Algorithm

 

HMAC-MD5- Message Digest 5

 

Note: Layer 4 policies require AES and HMAC-SHA-1.

Key Generation

Specifies the key generation and distribution mechanism for the PEPs included

 

in the policy.

 

• By Network Set - The default ETKMS within each network set generates

 

and distributes the keys to the PEPs included in those network sets.

 

• Global ETKMS - A global ETKMS generates the keys and sends them to

 

the default ETKMSs in each network set for distribution to all of PEPs

 

included in the policy.

 

Select the desired ETKMS from the Global ETKMS list.

Addressing

Overrides the Network addressing setting for the network sets.

Mode Override

• Preserve internal network addresses - This setting overrides the network

 

 

set’s network addressing mode and preserves the network addressing of the

 

protected networks. The IP header contains the source address of the

 

originating network.

 

If this setting is disabled and the addressing mode of the network set uses

 

the PEP’s remote IP address or a Virtual IP address, the IP header contains

 

the source address as specified in the network set. If the addressing mode

 

of the network set preserves the network IP address, disabling this setting

 

has no effect.

 

• Preserve address, protocol and port - This setting overrides the network

 

set’s addressing mode and preserves the network addressing of the

 

protected networks, as well as the specified protocol and port numbers. The

 

IP header includes the source address, protocol, and port of the originating

 

network. This allows you to send the Layer 4 header information in the clear

 

for traffic engineering and Service Level Agreement (SLA) management (for

 

example, Quality of Service controls).

Minimize Policy

Reduces policy size by ignoring the network addresses on the local port of the

Size

PEP. This reduces the amount of network traffic needed to renew keys and

 

refresh policy lifetimes.

 

• Minimize Policy Size (ignore source IP address) - This setting replaces

 

the source network address for outbound traffic and the destination network

 

address for inbound traffic with all networks wildcard addresses (0.0.0.0/0).

 

For more information, see “Minimizing Policy Size” on page 187.

Network Sets

Identifies the network sets included in this policy.

 

Click the Network Sets tab of the EncrypTight Components view and drag the

 

appropriate network sets to either Hubs or Spokes.

Protocol

Specifies the Layer 3 protocol affected by this policy. The action selected for

 

the policy is only applied to the traffic with the specified protocol.

 

• Any - specifies all protocols

 

• Only - specifies a particular protocol. Click to select and then enter the

 

required protocol in the range 0 to 255.
