DES-7200 Configuration Guide Chapter 6 BGP
Configuration
6-11
The process to enable the MD5 authentication on the BGP peer is shown as
follows:
Command Function
DES-7200(config-router)# neighbor
{address | peer-group-name}
password string
When the BGP connection with the
BGP peer is established, use this
command to enable the TCP MD5
authentication and set the password.
Use the no neighbor {ip-address | peer-group-name} password command to
disable the MD5 authentication set for the BGP peer (group).
Use the neighbor shutdown command to disable the valid connection
established with the BGP peer (group), and delete all route information related to
the BGP peer (group).
Caution
To tear down the connection established with the specified BGP peer (group)
and reserve the configuration information set for this specified BGP peer
(group), use the neighbor shutdown command. If such configuration
information is not required again, use the no neighbor [peer-group] command.
6.7 Configuring the Management Policy
Whenever the routing policy (including the distribute-list, neighbor route-map,
neighbor prefix-list and neighbor filter-list) changes, you need to take
effective measure to implement new routing policy. The traditional way is to tear
down and then reestablish the BGP session.
This product supports implementing 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
routing policy which has an effect on the input route information as the input
routing policy (such as the In-route-map and In-dist-list), and that has an effect
on the output route information as the output routing policy (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:
Command Function
DES-7200(config-router)# clear ip
bgp {* | neighbor address | peer-group
peer-group-name | external} soft out
Do soft reset of the BGP session and
execute the routing policy without
resetting up the BGP session.
If the input routing policy changes, its operation will be more complicated than
