Advanced Uses for Networks in Policies

clear.

ETPM accepts non-contiguous network masks, which allow you to create policies between particular addresses in your network. For example, a network of 10.0.0.1 with a mask of 255.0.0.255 allows all devices with an IP address of 10.x.x.1 to be managed by a particular policy. This feature is available only with ETEP PEPs. See “Using Non-contiguous Network Masks” on page 162 for more information.

If you are familiar with network addressing and network masks, you can use subnetting to make your policies more efficient.

●“Grouping Networks into Supernets” on page 161

Use supernetting to reduce the number of SAs and keys on each PEP in large deployments.

●“Using Non-contiguous Network Masks” on page 162

Use non-contiguous network masks to apply policies to a specific IP address scheme.

Grouping Networks into Supernets

Working with large networks, a considerable number of security associations (SAs) and keys can result on each PEP. One way to avoid this is to look for subnetworks within each network set that have contiguous addressing. You can combine these subnets to reduce the number of SAs and keys on each PEP.

In Figure 55, if you set up each of these networks as a separate network in ETPM, and the policy encrypts traffic between these two networks and five other networks, the PEP for this network set would contain 10 SAs and keys for each direction.

As illustrated in Figure 56, the two networks 192.168.2.0 with subnet mask 255.255.255.0 and 192.168.3.0 with subnet mask 255.255.255.0 could be grouped into one network 192.168.2.0 with subnet mask 255.255.254.0.
