6.12.22 Base Path Select ion on MEDs from Other Autonomous Systems
The MED is one of the parameters that is considered when select ing the best path among many
alternative paths. The path with a lower MED is preferred over a path with a higher MED.
By default, during the best-path select ion process, MED comparison is done only among paths from
the same autonomous system. You can allow comparison of MEDs among paths regardless of the
autonomous system from which the paths are received.
To do so, perform the following BGP configuration command:
bgp always-compare-med
In the prompt Select 1 option ，prompt is as below:
(00)always-compare-med
......
(03)cluster-id
......
Please Input the code of command to be excute(0-8): 0
input 0，Select always-compare-med option
6.12.23 Monitor and Maintain BGP
The administrator can display and delete the content in BGP routing table or other databases, and can
also display the detailed statistic information.
1. Clear the BGP Routing Table and Databases
The following table lists the tasks concerned with clearing the cache, the table or the BGP databases.
Use these commands in management mode:
rm ip bgp *
rm ip bgp as-number
rm ip bgp address
rm ip bgp address soft ｛in|out｝
rm ip bgp aggregates
rm ip bgp networks
rm ip bgp config-redistribute
Take the first command for an example.：
input clear Command，prompt is as below:
(00)arp-cache
(01)dialer
(02)frame-relay-inarp
(03)ip
Model Name
Command
Always compare MED
Route reflector cluster identifier
Command
Clear the entire ARP cache
Clear dialer statistics
Clear inverse ARP entries from the map table
IP
Allow the comparison of MEDs for paths
from neighbors in different autonomous
systems.
Reset all BGP connection.
Reset the BGP connection of the specified
autonomous system.
Reset the BGP connection of the specified
neighbor.
Clear the inbound or outbound database of
the specified neighbor.
Clear the route generated by the route
summary.
