FTOS Configuration Guide for the C-Series - Force10 Networks

• A neighbor is unconfigured
• clear ip bgp is issued
• New PDU are captured and there is no more space to store them
• The max buffer size is reduced. (This may cause PDUs to be cleared depending upon the buffer space
consumed and the new limit.)
With full internet feed (205K) captured, approximately 11.8MB is required to store all of the PDUs, as
shown in Figure 365.

PDU Counters
FTOS version 7.5.1.0 introduces additional counters for various types of PDUs sent and received from
neighbors. These are seen in the output of the command show ip bgp neighbor.
Sample Configurations
The following configurations are examples for enabling BGP and setting up some peer groups. These are
not comprehensive directions. They are intended to give you a some guidance with typical configurations.
You can copy and paste from these examples to your CLI. Be sure you make the necessary changes to
support your own IP Addresses, Interfaces, Names, etc.
