Layer 3 Configuration

This section includes the following topics:

●

“Interoperating with the Network” on page 47

You may need to configure other network settings in order for the ETEP to interoperate in the
network. These settings include reassembly of fragmented packets, DF bit handling, and DHCP relay
functionality.

●

“Configuring Transparent Mode for Layer 3 Policies” on page 52

Transparent mode is the ETEP’s default mode of operation and is appropriate for most Layer 3
distributed key policies. To use the ETEP in a Layer 3 virtual IP policy you must disabled transparent
mode operation and assign IP addresses to the local and remote ports.

Layer 3 configuration commands are available to the Admin user.

Interoperating with the Network

This section includes the following topics:

●

“Reassembling Fragmented Packets” on page 48

●

“DF Bit Handling” on page 49

●

“IPv6 Traffic Handling” on page 50
