E.
BGP dampening process
Explanation:
Cisco IOS XR allows you to control the configuration of the number of distributed speakers
and enables you to selectively assign neighbors to specific speakers. On the CRS-1 platform,
multiple speaker processes up to 15 may be configured. However, configuring all the
different speakers on the primary route processor simply adds to the load on the single RP.
Distributed speaker functionality is useful if Distributed Route Processor (DRP) hardware is
available to take advantage of process placement. Later sections in this chapter depict
distributed
BGP and placement of BGP process speakers on DRPs on a CRS-1 router.
In addition to the speaker process, BPM starts the bRIB process once BGP is configured.
bRIB process is responsible for performing the best-path calculation based on partial best
paths received from the speaker processes. The best route is installed into the bRIB and is
advertised back to all speakers. The bRIB process is also responsible for installing routes
