Parameters
capture bgp-pdu neighbor Enable capture of an IPv4 BGP neighbor packet.
capture bgp-pdu neighbor (ipv6) Enable capture of an IPv6 BGP neighbor packet.
show capture bgp-pdu neighbor Display BGP packet capture information for an IPv6 address on the

vrf vrf-name
Enter the keyword vrf and then the name of the VRF to clear all BGP sessions
corresponding to that VRF.
Note: Use this attribute to clear a BGP instance corresponding to either a
specific address family in a default VRF or an IPv4 address family in a a
non-default VRF.
*
Enter an asterisk ( * ) to reset all BGP sessions.
as-number
Enter the AS number to reset all neighbors belonging to that AS. The range is from 0
to 65535 (2 byte), from 1 to 4294967295 (4 byte), or from 0.1 to 65535.65535
(dotted format).
ip-address
Enter an IP address in dotted decimal format to reset all prefixes from that neighbor.
flap-statistics (OPTIONAL) Enter the keyword flap-statistics to reset the flap statistics on all
prefixes from that neighbor.
soft (OPTIONAL) Enter the keyword soft to configure and activate policies without
