Figure 18. BGP Routers in Full Mesh The number of BGP speakers each BGP peer must maintain increases exponentially. Network management quickly becomes impossible. Sessions and Peers When two routers communicate using the BGP protocol, a BGP session is started.

Establish a Session Information exchange between peers is driven by events and timers. The focus in BGP is on the traffic routing policies. In order to make decisions in its operations with other BGP peers, a BGP process uses a simple finite state machine that consists of six states: Idle, Connect, - Dell PowerSwitch S6000 | 9.50.1 Configuration Guide for the S6000 System - Page 155
Route reflection divides iBGP peers into two groups: client peers and nonclient peers. A route reflector and its client peers form a route reflection cluster. Because BGP speakers announce only the best route for a given prefix, route reflector rules are applied after the router makes its best path - Dell PowerSwitch S6000 | 9.50.1 Configuration Guide for the S6000 System - Page 156
in the BGP. Taking into account other constraints such as the Packet Size, maximum number of attributes are supported in BGP. Communities BGP communities are sets of routes with one or more common attributes. Communities are a way to assign common attributes to multiple routes - Dell PowerSwitch S6000 | 9.50.1 Configuration Guide for the S6000 System - Page 157

Because this number is the maximum limit supported on the device, the remaining six 40G ports are disabled.

This phenomenon occurs because in Release 9.4(0.0), static configuration for the restricted ports is maintained.

Figure 130. Buffer Tuning Points Deciding to Tune Buffers Dell Networking recommends exercising caution when configuring any non-default buffer settings, as tuning can significantly affect system performance.
