Parameters

Parameter	Description	Value
interface-type	Specifies the interface type.	-
interface-number	Specifies the interface number.	-
nexthop-address	Specifies the next hop address.	The value is in dotted decimal notation.
dhcp	Associates the static route with DHCP.	-
local-address address	Specifies the local address.	The value is in dotted decimal notation.
min-rx-interval min-rx-interval	Specifies the minimum interval at which BFD packets are received.	The value is an integer ranging from 3 to 20000, in milliseconds. The default value is 10.
min-tx-interval min-tx-interval	Specifies the minimum interval at which BFD packets are sent.	The value is an integer ranging from 3 to 20000, in milliseconds. The default value is 10.
detect-multiplier multiplier	Specifies the detection time multiplier.	The value is an integer ranging from 3 to 50. The default value is 3.
vpn-instance vpn-instance-name	Specifies the name of the VPN instance that the next hop belongs to.	The value is a string of 1 to 31 case-sensitive characters, spaces not supported. In addition, the VPN instance name must not be _public_. When double quotation marks are used around the string, spaces are allowed in the string.

Usage Guidelines

Usage Scenario

To configure BFD parameters for a static route, run the ip route-static bfd command.

Implementation Procedure

When setting BFD parameters for a static route, you need to specify the outbound interface or next hop.

Configuration Impact

To modify BFD parameters, you need to update BFD parameters of all the corresponding static routes.

If BFD parameters are configured, but the local-address ip-address parameter is not, BFD sessions may fail to be negotiated.

If the undo ipv6 route-static bfd command is run, the static route is unbound from all BFD sessions. Therefore, exercise caution when running the command.

Precautions

When configuring BFD for a single route, you need to check whether the BFD parameters of the static route are set.
Search for BFD parameters according to the outbound interface, next hop, and VPN instance that the next hop belongs to for the static route.
If min-rx-interval, min-tx-interval, or detect-multiplier are not set, default values of BFD parameters are used.
When you configure BFD parameters for a static VPN route, specifying a VPN instance and specifying an outbound interface are mutually exclusive. If an outbound interface is specified in this configuration, the VPN instance created on the next hop is used as the VPN instance bound to the outbound interface.

Example

# Set the next hop address to 1.2.3.4, the local address to 11.11.11.1, and the minimum interval at which BFD packets are received to 30 ms for a static route.
