clear ip bgp dampening

Syntax

To clear IP-specific information for only the route-target address family:

clear ip bgp route-target signaling { dampening | flap-statistics } [ rtfPrefix
| rtfAddress ]

To clear IP-specific information for any case other than for the route-target address family:

clear ip bgp
[ vrf vrfName ] [ ipv4 unicast | ipv4 multicast | vpnv4 unicast |
l2vpn all | l2vpn vpls vplsName | l2vpn vpws vpwsName]
{ dampening | flap-statistics } [ ipAddress [ addressMask ] ]

Release Information

Command introduced before JunosE Release 7.1.0.
l2vpn keyword added in JunosE Release 7.1.0.
vpls keyword and vplsName variable added in JunosE Release 7.1.0.
all, vpws, and route-target signaling keywords and rtMemNlri and vpwsName variables added in JunosE Release 8.2.0.
rtMemNlri variable replaced by two variables, rtfAddress and rtfPrefix, in JunosE Release 9.1.0.

Description

Clears IP route flap dampening information and reinstates the suppressed routes. The dampening keyword and the flap-statistics keyword both have the same effect. There is no no version.

Options

• route-target signaling—Clears the route-target membership information
• rtfPrefix—Prefix representing the route-target membership NLRI (RT-MEM-NLRI), in the format asNumber : extendedCommunity / prefixLength (for example, 320:320:524/36) where:
  • asNumber—AS number for origin of route target information, in the range 1–4294967295
  • extendedCommunity—Two-part number in the format number1:number2 that identifies an extended community of VPNs, in the format number1 : number2, where:
  • number1—Autonomous system (AS) number, in the range 1–4294967295, or an IP address
  • number2—Unique integer, in the range 1–4294967295; 32 bits if number1 is a 16-bit AS number; 16 bits if number1 is an IP address or a 32-bit AS number
  • prefixLength—Number that specifies the length of the route prefix, in the range 32–96
• rtfAddress—rtfPrefix with a prefix length of 96; representing the route-target membership NLRI (RT-MEM-NLRI), in the format asNumber: extendedCommunity (for example, 320:320:524 or 320:50.2.3.4:524)
• vrfName—Name of a virtual routing and forwarding instance to clear
• ipv4 unicast—Clears the IPv4 unicast routing table; the default option
• ipv4 multicast—Clears the IPv4 multicast routing table
• vpnv4 unicast—Clears the VPNv4 unicast routing and forwarding table
• l2vpn all—Clears the L2VPN reachability information for all VPLS and VPWS instances in the L2VPN address family
• l2vpn vpls vplsName—Clears the L2VPN reachability information for the VPLS instance with the name vplsName
• l2vpn vpws vpwsName—Clears the L2VPN reachability information for the VPWS instance with the name vpwsName
• ipAddress—IP address of the BGP neighbor to clear
• addressMask—Address mask to be applied to the network IP address
