C HAPTER 51 | IP Routing Commands
Border Gateway Protocol (BGPv4)
– 1879 –
DEFAULT SETTING
None
COMMAND USAGE
◆ This command terminates any active sessions for the specified
neighbor, and removes any associated routing information.
◆ Use the show ip bgp summary command display the neighbors which
have been administratively shut down. Entries with in an Idle (Admin)
state have been disabled by the neighbor shutdown command.
EXAMPLE
Console(config-router)#neighbor 10.1.1.66 shutdown
Console(config-router)#
neighbor soft-
reconfiguration
inbound
This command configures the switch to store updates in the inbound
message buffer, and perform soft re-configuration from this buffer for
specified neighbors when required. Use the no form to disable this feature.
SYNTAX
[no] neighbor {ip-address | group-name} soft-reconfiguration
inbound
ip-address – IP address of a neighbor.
group-name – A BGP peer group containing a list of neighboring
routers configured with the neighbor peer-group command.
COMMAND MODE
Router Configuration
DEFAULT SETTING
Disabled
COMMAND USAGE
◆ Use this command to employ soft reconfiguration for a neighbor. A hard
reset clears and rebuilds specified peering sessions and routing tables.
Soft reconfiguration uses stored information to reconfigure and activate
routing tables without clearing existing sessions. It uses stored update
information to allow you to restore a connection or to apply a new BGP
policy without disrupting the network. Note that outbound soft
reconfiguration does not require inbound soft reconfiguration to be
enabled.
◆ The command is only available when route refresh capability is not
enabled. Route refresh (RFC 2918) allows a router to reset inbound
routing tables dynamically by exchanging route refresh requests with
peers. Route refresh relies on the dynamic exchange of information
with supporting peers. It is advertised through BGP capability
negotiation, and all BGP routers must support this capability.
