Configures no route flap dampening for a BGP peer group (disables route flap dampening).
| peer-group-name | Specifies a BGP peer group. |
| 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, IPv4 unicast is the default.
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
If the specified peer group contains IPv6 peers, it is an IPv6 peer group and you must specify an IPv6 address-family. When the specified peer group is an IPv6 peer group, this command fails if no address family is specified or if an IPv4 address-family is specified. This command also fails if an IPv6 address family is specified for an IPv4 peer-group.
Use the following command to enable route flap dampening for a BGP peer-group:
configure bgp peer-group peer-group-name {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-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 peer group outer:
configure bgp peer-group outer 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 Switch Engine v33.1.1 Licensing Guide document.
