The ip-address parameter is the neighbor IP address. The following sub-parameters are available for
the ip-address parameter:
[advertised routes} [flap-statistics] [last-packet-with-error] [received] [received-routes] [rib-out-
routes] [routes][routes-summary]
The advertised-routes parameter displays routes advertised to a neighbor. The flap-statistics
parameter displays flap statistics for a neighbor. The last-packet-with-error parameter displays the
last packet received with error. The received parameter displays the received ORF from neighbor.
The received-routes parameter displays the received routes from neighbor. The rib-out-routes
parameter displays RIB-out routes for a neighbor.The routes parameter displays routes learned from
neighbor. The routes-summary parameter displays routes summary for a neighbor.
Clearing IPv6 route information
To clear IPv6 unicast route information with respect to IPv4 neighbors, enter the clear ip bgp ipv6
neighbor command.
Syntax: clear ip bgp ipv6 [neighbor ] [as-number | ipaddress | peer-group-name | all]
The dampening parameter clears route flap dampening information. The flap-statistics parameter
clears route flap statistics.
The local parameter clears local information. The routes parameter clears BGP routes. The traffic
parameter clears BGP traffic counters. The ipv6 parameter clears information for ipv6 address family.
The vpnv4 parameter clears information for VPNV4 address family. The vrf parameter clears
information for a VRF instance.
The neighbor parameter has the following sub-parameters:
as-number identifies neighbors with the specified AS number, 1-4294967295. ipaddress identifies the
neighbor IP address. peer-group-name clears the peer group name identified using ASCII string. all
clears all BGP neighbors.
Adding a BGP4 peer group
A peer group is a set of BGP4 neighbors that share common parameters. The benefits of peer groups
are:
• Simplified neighbor configuration - You can configure a set of neighbor parameters and then apply
them to multiple neighbors. You do not need to configure the common parameters individually on
each neighbor.
• Flash memory conservation - Using peer groups instead of individually configuring all the
parameters for each neighbor requires fewer configuration commands in the startup configuration
file.
You can perform the following tasks on a peer-group basis:
• Reset neighbor sessions
• Perform soft-outbound resets (the device updates outgoing route information to neighbors but does
not entirely reset the sessions with those neighbors)
• Clear BGP4 message statistics
• Clear error buffers
Peer group parameters
You can set all neighbor parameters in a peer group. When you add a neighbor to the peer group, the
neighbor receives all the parameter settings you set in the group, except parameter values you have
