ip route static bfd

Configures a Bidirectional Forwarding Detection (BFD) session for a static IPv4 route.

Syntax

ip route static bfd dest-ip-address source-ip-address[interval transmit-time min-rx receive-time multiplier number]
no ip route static bfd dest-ip-address src-ip-address

Command Default

By default, BFD is not configured for an IPv4 static route.

Parameters

dest-ip-address
Specifies the IPv4 address of the BFD neighbor.
source-ip-address
Specifies the source IPv4 address.
intervaltransmit-time
Specifies the interval, in milliseconds, a device waits to send a control packet to BFD peers. Valid values range from 50 through 30000. The default is 300 milliseconds.
min-rx receive-time
Specifies the interval, in milliseconds, a device waits to receive a control packet from BFD peers. Valid values range from 50 through 30000. The default is 300 milliseconds.
multiplier number
Specifies the number of consecutive BFD control packets that must be missed from a BFD peer before BFD determines that the connection to that peer is not operational. Valid values range from 3 through 50. The default is 3.

Modes

Global configuration mode

Address-family IPv4 unicast VRF configuration mode

Usage Guidelines

The local device needs the interval transmit-time and min-rx receive-time variables. The actual values in use will be the negotiated values.

For single-hop static BFD sessions, the interval value is taken from the outgoing interface. For multi-hop BFD sessions, if the configured interval and min-rx parameters conflict with those of an existing session, the lower values are used.

Use the no form of the command to remove the configured static route.

Examples

This example configures a BFD session on an IPv4 static route. 

device# configure terminal
device(config)#)# ip route static bfd 10.0.2.1 10.1.1.1 interval 500 min-rx 500 multiplier 5

This example configures a BFD session on an IPv4 static route in a non-default VRF instance. 

device# configure terminal
device(config)# vrf orange
device(config-vrf-orange)# address-family ipv4 unicast
device(vrf-ipv4-unicast)# ip route static bfd 10.2.2.2 10.3.3.3 interval 600 min-rx 700 multiplier 10
