Enable BFD for BGPv6 Peers
About this task
BFD provides a failure-detection mechanism between two systems. Use the following procedure to enable BFD for BGPv6 peers.
Note
Enabling BFD at the application level does not establish a BFD session. To establish a BFD session, you must enable BFD globally and at the interface level.Note
BFD for IPv6 interfaces is a demonstration feature on some products. For more information about feature support, see Fabric Engine Feature Support Matrix.
Procedure
- In the navigation pane, expand .
- Select BGP+.
- Select the Peers tab.
- Select Insert.
- Select BfdEnable.
Peers Field Descriptions
Use the data in the following table to use the Peers tab.
Name |
Description |
---|---|
RemoteAddr |
Specifies the remote IPv6 address of the entered BGP+ peer. |
GroupName |
Specifies the peer group name to which the peer belongs (optional). |
PeerState |
Specifies the BGPv6 peer connection state. |
RemoteAs |
Configures a remote AS number for the peer or peer-group in the range 0 to 65535. |
Enable |
Controls whether the peer connection is enabled or disabled. The default is disabled. |
EbgpMultiHop |
Enables or disables a connection to a BGPv6 peer that is more than one hop away from the local router. The default value is disable. |
RoutePolicyIn |
Specifies the policy (by name) that applies to all network routes learned from this peer. |
RoutePolicyOut |
Specifies the policy (by name) that applies to all outgoing route updates. |
RemovePrivateAs |
Strips (when enabled) private AS numbers when the switch sends an update. The default is enable. |
UpdateSourceInterface |
Specifies the source IP address to use when the switch sends eBGP packets to this peer or peer group. |
ConnectRetryInterval |
Specifies the time interval, in seconds, for the connect retry timer. The suggested value for this timer is 120 seconds. The range is 1 to 65535. |
HoldTimeConfigured |
Specifies the time interval, in seconds, for the hold time for this BGP speaker with this peer. This value is in an open message sent to this peer by this BGP speaker. To determine the hold time with the peer, the switch compares this value with the HoldTime value in an open message received from the peer. The HoldTime must be at least three seconds. If the value is zero, the hold time does not establish with the peer. The suggested value for this timer is 180 seconds. The range is 0 to 65535. |
KeepAliveConfigured |
Specifies the time interval, in seconds, for the KeepAlive timer configured for this BGP speaker with this peer. KeepAliveConfigured determines the keep alive message frequency relative to HoldTimeConfigured; KeepAlive indicates the actual time interval for the keep alive messages. The maximum value for this timer is one-third of HoldTimeConfigured. If KeepAliveConfigured is zero, no periodic keep alive messages are sent to the peer after the peers establish a BGP connection. Configure a value of 60 seconds. The range is 0 to 21845. |
MD5Authentication |
Enables and disables MD5 authentication. |
AdvertisementInterval |
Specifies the time interval, in seconds, that elapses between each transmission of an advertisement from a BGPv6 neighbor. The default value is 30 seconds and the range is 5 to 120 seconds. The route advertisement interval feature is implemented using the time stamp that indicates when each route is advertised. The time stamp is marked to each route so that the route advertisement interval is compared to the time stamp and BGP is then able to make a decision about whether the route advertisement can be sent or should be delayed when a better route is received. This feature does not work for a withdraw route because the route entry is already removed when the processing route advertisement is sent and the time stamp marked in the route entry cannot be obtained. |
DefaultOriginateIpv6 |
When enabled, specifies that the current IPv6 route originated from the BGP peer. This parameter enables or disables sending the default IPv6 route information to the specified neighbor or peer. The default value is false. |
Weight |
Specifies the peer or peer group weight, or the priority of updates the system can receive from this BGP peer. The default value is 100 and the range is 0 to 65535. |
MaxPrefix |
Configures a limit on the number of routes accepted from a neighbor. The default value is 12000 routes and the range is 0 to 2147483647. A value of 0 means no limit exists. |
NextHopSelf |
Specifies that the next-hop attribute in an iBGP update is the address of the local router or the router that generates the iBGP update. The default is disable. |
RouteReflectorClient |
Specifies that this peer is a route reflector client. Note:
This parameter only applies to VRF 0. |
SoftReconfigurationIn |
When enabled, the router relearns routes from the specified neighbor or group of neighbors without restarting the connection after the policy changes in the inbound direction. The default value is disable. Enabling SoftReconfigurationIn stores all BGP routes in local memory (even non-best routes). |
DebugMask |
Displays the specified debug information for the BGP peer. The default value is none.
|
SendCommunity |
Enables or disables sending the community attribute of the update message to the specified peer. The default value is disable. |
IpvpnLiteCap |
Enable or disable IP VPN-lite capabilitiy on the BGP neighbor peer. |
Ipv6Cap |
Enable or disable the IPv6 capability on the BGP neighbor peer. The default value is disable. |
RouteRefresh |
Enables or disables route refresh. If enabled, a route refresh request received by a BGP speaker causes the speaker to resend all route updates in the database that are eligible for the peer that issues the request. This parameter only applies to VRF 0. |
AsOverride Note:
This field does not apply to 5320 Series switches. |
Specifies that the AS Override parameter can be enabled or disabled for the BGP peer. The default is disable. |
AllowAsIn Note:
This field does not apply to 5320 Series switches. |
Specifies the number of AS-in allowed for the BGP peer. The range is 1–10. |
Ipv6RoutePolicyIn |
Specifies the policy (by name) that applies to all network IPv6 routes learned from this peer. |
Ipv6RoutePolicyOut |
Specifies the policy (by name) that applies to all outgoing IPv6 route updates. |
Ipv6MaxPrefix |
Configures a limit on the number of IPv6 routes accepted from a neighbor. A value of 0 means no limit exists. |
BfdEnable |
Enables Bidirectional Forwarding Detection (BFD) for this peer. |
