DGS-3610 Series Configuration Guide Chapter 29 BGP Configuration
To disable the connection established with specified peer (group) and
reserve the configuration information set for this specified peer (group),
use the neighbor shutdown command. If such configuration information
is not required again, use the no neighbor [peer-group] command.
29.5 Configuring Management Policy
for BGP
Once the routing policy (including the distribute-list, neighbor route-map, neighbor
prefix-list and neighbor filter-list) changes at any time, it is necessary to take effective
measure to implement new route policies. Traditional measure is to close it and reestablish
new BGP connection.
This product supports to implement new routing policy without the close of the BGP session
connection by the configuration of the soft reset for BGP effectively.
To facilitate the description of the BGP soft reset, the following will refer to the route policy
which has an effect on the input route information as the input route policy (such as the
In-route-map and In-dist-list), and that has an effect on the output route information as the
output route strategy (such as the Out-route-map and Out-dist-list).
If the output routing policy changes, execute the following operations in the BGP
configuration mode:
Router(config-router)# clear ip bgp
{* | neighbor address | peer-group
peer-group-name | external} soft out
For the soft reset BGP connection, it is not necessary
to restart the BGP Session and activate the implement
of the route policy.
If the input route policy changes, its operation will be more complicated than that of the
output route policy: For the implement of the output routing policy is based on the route
information table of this BGP Speaker. The implement of the input routing policy is based on
the route information received from the BGP Peer. To reduce the memory consumption, the
local BGP Speaker will not remain the original route information received from BGP Peers.
If it is necessary to modify the input routing policy, the common method is to save the original
route information for each specified BGP peer in this BGP Speaker by the neighbor
soft-reconfiguration inbound command, so as to provide the original foundation of the
route information to modify the input route policy in the future.
At present, there is a standard implement method referred to as the Route Refresh
Performance, which can support to modify the route policy without the storage of the original
route information. This product supports the route refreshing performance.
If the input route policy changes, execute the following operations in the BGP configuration
mode:
