Configures no route flap dampening over BGP (Border Gateway Protocol) peer sessions (disables route flap dampening).
| remoteaddr | Specifies the IPv4 or IPv6 address of a BGP neighbor. The switch uses the IP address format to determine if the address is an IPv4 or IPv6 address. |
| all | Specifies that the configuration applies to all neighbors in the specified address family. If no address family is specified or if an IPv4 address is specified, the configuration applies to all IPv4 neighbors. If an IPv6 address family is specified, the configuration applies to all IPv6 neighbors. |
| ipv4-unicast | Specifies the IPv4 unicast address family. |
| ipv4-multicast | Specifies an IPv4 multicast address family. |
| ipv6-unicast | Specifies the IPv6 unicast address family. |
| ipv6-multicast | Specifies an IPv6 multicast address family. |
| vpnv4 | Specifies the VPNv4 address family for Layer 3 VPN support. |
This feature is disabled by default.
If no address family is specified and an IPv4 address is detected, IPv4 unicast is the default address family.
If you do not specify an address family, this command applies to the IPv4 unicast address family. To apply this command to an address family other than the IPv4 unicast address family, you must specify the address family.
Note
For an IPv6 peer, an IPv6 address family must be specified, because an IPv6 peer does not support IPv4 address families. If no address family is specified for an IPv6 peer, the default, the IPv4 unicast address family, applies and the command fails. Similarly an IPv4 peer only supports IPv4 address families and the command fails if an IPv6 address family is specified.
Use the following command to enable route flap dampening for BGP neighbors:
configure bgp neighbor [all | remoteaddr] {address-family [ipv4-unicast | ipv4-multicast | ipv6-unicast | ipv6-multicast | vpnv4]} dampening {{half-life half-life-minutes {reuse-limit reuse-limit-number suppress-limit suppress-limit-number max-suppress max-suppress-minutes} | policy-filter [policy-name | none]}To configure this feature on Layer 3 VPNs, you must configure this feature in the context of the MPLS (Multiprotocol Label Switching)-enabled VR; this feature is not supported for BGP neighbors on the CE (VRF) side of the PE router.
The following command disables route flap dampening to the BGP neighbor at 192.168.1.22:
configure bgp neighbor 192.168.1.22 no-dampening
This command was first available in ExtremeXOS 10.1.
This command required a specific license in ExtremeXOS 11.1.
Support for IPv6 was added in ExtremeXOS 12.6 BGP.
Support for Layer 3 VPNs was added in ExtremeXOS 15.3.This command is available on platforms that support the appropriate license. For complete information about software licensing, including how to obtain and upgrade your license and which licenses support the BGP feature, see the ExtremeXOS 22.2 Feature License Requirements document.
