Level: 8. (
EI Mode Only Command

Usage Guideline
This command can be used to initiate a hard reset or soft reconfiguration of eBGP
neighbor sessions.
If a hard reset is applied to the inbound session, the inbound session will be torn
down and the local inbound routing table and the remote outbound routing table will
be cleared.
If a soft reset is applied to the inbound session, the session will not be rebuilt but the
local inbound routing table will be cleared and needs to be rebuilt.
If a soft reconfiguration inbound is enabled, then the routing table can be rebuilt
based on the stored route updates information. If a soft reconfiguration inbound is
disabled, then the local router will send the route refresh request to the neighbor to
ask for the route refresh.
When the inbound session undergoes a soft reset with the prefix filter option, and the
‘capability_orf_prefix_list’ parameter is enabled in the sending direction, then the
local BGP will send a ‘clear the routing table’ message, and notify the remote
neighbor for the prefix filter.
This is a way to notify the neighbor of the prefix filter whenever a change is made to
the prefix filter.
Example
The following example, a soft reconfiguration is configured for all inbound eBGP
peering sessions.
DXS-3600-32S#clear ip bgp external soft in
DXS-3600-32S#
Example
This example shows how to send a prefix filter to a neighbor and let the neighbor re-
advertisement BGP routes, based on the new prefix filter. The neighbor capability of
the prefix-list in the sending direction needs be configured, and that the local filter list
in the inbound direction for the peer needs be set.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)#router bgp 100
DXS-3600-32S(config-router)#neighbor 172.16.10.1 remote-as 200
