The following example shows how to view space requirements for storing all the PDUs. With full internet feed
(205K) captured, approximately 11.8MB is required to store all of the PDUs.

PDU Counters
Dell Networking OS supports additional counters for various types of PDUs sent and received from neighbors.
These are seen in the output of the
show ip bgp neighbor
command.
Sample Configurations
The following example configurations show how to enable BGP and set up some peer groups. These
examples are not comprehensive directions. They are intended to give you some guidance with typical
configurations.
To support your own IP addresses, interfaces, names, and so on, you can copy and paste from these
examples to your CLI. Be sure that you make the necessary changes.
The following illustration shows the configurations described on the following examples. These
configurations show how to create BGP areas using physical and virtual links. They include setting up the
interfaces and peers groups with each other.
