# 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

#### Mode

Privileged Exec
