in
(Optional) Specifies to initiate a soft reset for inbound routing information.
prefix-filter
(Optional) Specifies to clear the existing outbound route filter (ORF) prefix list to
trigger a new route refresh or soft reconfiguration, which updates the ORF prefix list.
out
(Optional) Specifies to initiate a soft reset for outbound routing information.
Default
None.
Command Mode
Privileged Mode.
Command Default Level
Level: 8. (
EI Mode Only Command

Usage Guideline
This command is used to initiate a hard reset or a soft reset for a set of connections.
A hard reset tears down and rebuilds all the sessions for the members of the
specified peer group and clears and rebuilds the local routing table. A soft reset only
clears and rebuilds the local routing table.
To the soft reset, if neighbor soft-reconfiguration inbound is configured, the routing
table can be rebuilt based on the stored route updates information, and if it doesn’t,
the local router will send the route refresh message to the neighbors to ask for the
routes.
When the inbound session is soft reset with the prefix-filter option, and the neighbor
capability orf prefix-list in the send direction is configured, the local BGP will send
“clear the routing table”, and notify the remote neighbor for the prefix filter.
When using the
clear ip bgp peer-group
PEER-GROUP-NAME
command without
the soft parameter, the BGP connection will be torn down, so the following log
message will be generated.
[BGP(2):] BGP connection is normally closed (Peer:<ipaddress>)
Where the <ipaddress> is the address of the peer. After a while, the connection will
be rebuilt, and the following log message will be generated.
[BGP(1):] BGP connection is successfully established Peer:<ipaddress>
Where the <ipaddress> is the address of the peer.
This is a way to notify the neighbor of the prefix filter whenever a change is made to
the prefix filter.
Example
In the following example, all members of the BGP peer group named ‘INTERNAL’
will reset.
DXS-3600-32S#clear ip bgp peer-group INTERNAL
DXS-3600-32S#
Example
In the following example, a soft reconfiguration is initiated for both the inbound and
outbound session with members of the peer group INTERNAL.
DXS-3600-32S#clear ip bgp peer-group INTERNAL soft
DXS-3600-32S#
Example
When using the parameter soft with either in or out, the soft reconfiguration is only
initiated for the inbound or outbound session.
Assume that the neighbor capability of the ‘prefix-list’ in the send direction is
configured, and that the local filter list in the inbound direction for the peer group is
changed, using this command with parameters soft in prefix-filter to notify all the
neighbors in the peer group.
DXS-3600-32S#clear ip bgp peer-group INTERNAL soft in prefix-filter
