# show ip bgp flap-statistics

#### Syntax

To display information about dampened routes for address families other than the L2VPN and route-target signaling address families:

show ip bgp
[ ipv4 unicast | ipv4 multicast | vpnv4 all | vpnv4 vrf vrfName ] flap-statistics
[ network [ networkMask ] ] [ filter ]

To display information about dampened routes for only the route-target signaling address family:

show ip bgp route-target signaling flap-statistics [ rtfPrefix | rtfAddress ] [ filter ]

To display information about dampened routes for only the L2VPN address family:

show ip bgp
{ l2vpn all | l2vpn vpls vplsName | l2vpn vpws vpwsName } flap-statistics
[ site-id siteId block-offset blockOffset ] [ filter ]

block-offset keyword and blockOffset variable added in JunosE Release 7.1.0.
vpws keyword and vpwsName variable added in JunosE Release 8.1.0.
route-target signaling keywords and rtMemNlri variable added in JunosE Release 8.2.0.
rtMemNlri variable replaced by two variables, rtfAddress and rtfPrefix, in JunosE Release 9.1.0.

#### Description

Displays information about routes that are dampened.

#### Options

- ipv4 unicast—Specifies the IPv4 unicast address family and routing table; the default option
- ipv4 multicast—Specifies the IPv4 multicast address family and routing table
- vpnv4 all—Specifies the IPv4 VPN address family and all IPv4 VPN routing and forwarding instances
- vpvn4 vrf vrfName—Specifies the IPv4 VPN address family and only the IPv4 VPN routing and forwarding instance with the name vrfName
- network—IP address of the network for which you want information displayed; if no network is specified, the fields are displayed for all networks
- networkMask—Address mask to be applied to the network address
- route-target signaling—Displays information for only the route-target address family
- 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)
- l2vpn all—Specifies all VPLS and VPWS instances in the L2VPN address family
- l2vpn vpls vplsName—Specifies the VPLS instance with the name vplsName
- l2vpn vpws vpwsName—Specifies the VPWS instance with the name vpwsName
- siteId—Numerical identifier for the site; must be an unsigned 16-bit integer greater than zero that is unique across the VPLS domain
- blockOffset—Integer in the range 1–65535 that identifies a block offset for which information is displayed
- filter—See Filtering show Commands
