| Exam 642-885 | Question id=3326 | BGP Routing Features in a Service Provider IP NGN Environment |
You noticed a recent change to the BGP configuration on a PE router, the bgp scan time has been changed from the default value to 30s. Which three effects will this change have?
| A. |
The BGP table will be examined and verified more frequently | |
| B. |
The BGP keepalive messages will be sent to the BGP peers at a faster rate | |
| C. |
The BGP table will be modified more quickly in the event that a next-hop address becomes unreachable | |
| D. |
The CPU load of the router will increase | |
| E. |
The minimum time interval between sending EBGP and IBGP routing updates will decrease | |
| F. |
The BGP convergence time will increase |
To configure scanning intervals of Border Gateway Protocol(BGP) routers for next hop validation or to decrease import processing time of Virtual Private Network version 4 (VPNv4) routing information, use the bgp scan-time command in address family or router configuration mode. To return the scanning interval of a router to its default scanning interval of 60 seconds, use the no form of this command.
bgp scan-time [import] scanner-interval
no bgp scan-time [import] scanner-interval
import - (Optional) Configures import processing of VPNv4 unicast routing information from BGP routers into routing tables.
scanner-interval - The scanning interval of BGP routing information.(Valid values are from 15 to 60 seconds. The default is 60 seconds)
