ip route static bfd
The group keyword assigns a BFD group. The static BFD configuration is added to the VPN routing and
forwarding (VRF) instance with which the interface is associated. The passive keyword specifies the passive
member of the group. Adding static BFD in a group without the passive keyword makes the BFD an active
member of the group. A static route should be tracked by the active BFD configuration in order to trigger a
BFD session for the group. To remove all the static BFD configurations (active and passive) of a specific
group, use the no ip route static bfd command and specify the BFD group name.
The unassociate keyword specifies that a BFD neighbor is not associated with static route, and the BFD
sessions are requested if an interface has been configured with BFD. This is useful in bringing up a BFDv4
session in the absence of an IPv4 static route. If the unassociate keyword is not provided, then the IPv4 static
routes are associated with BFD sessions.
BFD requires that BFD sessions are initiated on both endpoint devices. Therefore, this command must be
configured on each endpoint device.
The BFD static session on a switch virtual interface (SVI) is established only after the bfd interval milliseconds
min_rx milliseconds multiplier multiplier-value command is disabled and enabled on that SVI.
To enable the static BFD sessions, perform the following steps:
1 Enable BFD timers on the SVI.
bfd interval milliseconds min_rx milliseconds multiplier multiplier-value
2 Enable BFD for the static IP route
ip route static bfd interface-type interface-number ip-address
3 Disable and enable the BFD timers on the SVI again.
no bfd interval milliseconds min_rx milliseconds multiplier multiplier-value
bfd interval milliseconds min_rx milliseconds multiplier multiplier-value
Examples The following example shows how to configure BFD for all static routes through a specified neighbor, group,
and active member of the group:
Device# configuration terminal
Device(config)# ip route static bfd GigabitEthernet 1/0/1 10.1.1.1 group group1
The following example shows how to configure BFD for all static routes through a specified neighbor, group,
and passive member of the group:
Device# configuration terminal
Device(config)# ip route static bfd GigabitEthernet 1/0/1 10.2.2.2 group group1 passive
The following example shows how to configure BFD for all static routes in an unassociated mode without
the group and passive keywords:
Device# configuration terminal
Device(config)# ip route static bfd GigabitEthernet 1/0/1 10.2.2.2 unassociate
