If used without a qualifier, the keyword resets all neighbors belonging to that AS. Range: 1 to 65535 (OPTIONAL) Enter the keyword flap-statistics to clear all flap statistics belonging to that AS or a specified address family within that AS. (OPTIONAL) Enter the keyword ipv4 to select options for that address family. (OPTIONAL) Enter the keyword ipv6 to select options for that address family. (OPTIONAL) Enter the keyword unicast to select the unicast option within the selected address family. (OPTIONAL) Enter the keyword multicast to select the multicast option within the selected address family. Multicast is supported on IPv4 only (OPTIONAL) Enter the keyword soft to configure and activate policies without resetting the BGP TCP session, that is, BGP Soft Reconfiguration. Note: If you enter clear ip bgp ipv6-address soft, both inbound and outbound policies are reset. (OPTIONAL) Enter the keyword in to activate only inbound policies. (OPTIONAL) Enter the keyword out to activate only outbound policies. Version 8.3.19.0 Version 8.4.2.1 Version 8.2.1.0 Version 7.4.1.0 Introduced on S4820T Introduced on C-Series and S4810 Introduced on E-Series ExaScale Introduced on E-Series TeraScale clear ip bgp ipv6-address c e Reset BGP sessions specific to an IPv6 address on the E-Series. The soft parameter (BGP Soft Reconfiguration) clears the policies without resetting the TCP connection.
