Administrator Guide

If you specify a BGP peer group by using the peer-group-name argument, all members of the peer group inherit the characteristic
configured with this command.
• Clear all information or only specific details.
EXEC Privilege mode
clear ip bgp {* | neighbor-address | AS Numbers | ipv4 | peer-group-name} [soft [in | out]]
• *: Clears all peers.
• neighbor-address: Clears the neighbor with this IP address.
• AS Numbers: Peers’ AS numbers to be cleared.
• ipv4: Clears information for the IPv4 address family.
• peer-group-name: Clears all members of the specified peer group.
• Enable soft-reconfiguration for the BGP neighbor specified.
CONFIG-ROUTER-BGP mode
neighbor {ip-address | peer-group-name} soft-reconfiguration inbound
BGP stores all the updates received by the neighbor but does not reset the peer-session.
Entering this command starts the storage of updates, which is required to do inbound soft reconfiguration. Outbound BGP soft
reconfiguration does not require inbound soft reconfiguration to be enabled.
The example enables inbound soft reconfiguration for the neighbor 10.108.1.1. All updates received from this neighbor are stored
unmodified, regardless of the inbound policy. When inbound soft reconfiguration is done later, the stored information is used to generate a
new set of inbound updates.

Enabling or disabling BGP neighbors
You can enable or disable all the configured BGP neighbors using the shutdown all command in ROUTER BGP mode.
To disable all the configured BGP neighbors:
1. Enter the router bgp mode using the following command:
CONFIGURATION Mode
router bgp as-number
2. In ROUTER BGP mode, enter the following command:
ROUTER BGP Mode
shutdown all
You can use the no shutdown all command in the ROUTER BGP mode to re-enable all the BGP interface.
You can also enable or disable BGP neighbors corresponding to the IPv4 unicast or multicast groups and the IPv6 unicast groups.
To enable or disable BGP neighbors corresponding to the IPv4 unicast groups:
1. Enter the router bgp mode using the following command:
CONFIGURATION Mode
router bgp as-number
2. Shut down the BGP neighbors corresponding to the IPv4 unicast groups using the following command:
shutdown address-family-ipv4-unicast
To enable or disable BGP neighbors corresponding to IPv4 multicast groups:
1. Enter the router bgp mode using the following command:
Border Gateway Protocol IPv4 (BGPv4)
