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 ]

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.
interval transmit-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.

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
