Adding Layer 3 IP Policies

 

 

 

Table 50

Multicast 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 global ETKMS used in the multicast network. 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 ETKMS list.

 

 

 

 

Addressing

Overrides the Network addressing setting for the network sets.

 

Mode Override

• Preserve internal network addresses - This setting is always enabled for

 

 

 

 

 

 

multicast policies and cannot be disabled. By default, multicast policies

 

 

 

override network set’s network addressing mode and preserve the network

 

 

 

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

 

 

 

address of the originating network.

 

 

 

• 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) - This setting replaces the source

 

 

 

network address for outbound traffic with an all networks wildcard address

 

 

 

(0.0.0.0/0). For more information, see “Minimizing Policy Size” on page 187.

 

 

 

 

Multicast

Identifies the multicast address range protected by this policy.

 

Network

• IP - multicast IP address

 

 

 

Mask - mask for the multicast IP address

Network Sets Identifies the networks included in this policy.

Click on the Network Sets tab of the EncrypTight Components view and drag the appropriate network sets to the desired columns.

Send - lists the networks that only send data

Receive - lists the networks that only receive data

Send and Receive - lists the networks that send and receive data

ETPM supports technologies such as Protocol Independent Multicast (PIM) by providing the ability to have multiple senders, receivers, and senders/receivers in multicast policies.
