Configuring BFD Under a Dynamic Routing Protocol or Using a Static Route
Purpose
Enters static route configuration mode, allowing you to configure
static routing.
Enables BFD fast-detection on the specified IPV4 unicast destination
address prefix and on the forwarding next-hop address.
• Include the optional minimum-interval keyword and argument
to ensure that the next-hop is assigned with the same hello
interval. Replace the interval argument with a number that
specifies the interval in milliseconds. Range is from 10 through
10000.
• Include the optional multiplier keyword argument to ensure
that the next hop is assigned with the same detect multiplier.
Replace the multiplier argument with a number that specifies
the detect multiplier. Range is from 1 through 10.
Note
Specifies a VPN routing and forwarding (VRF) instance, and enters
static route configuration mode for that VRF.
Enables BFD fast-detection on the specified IPV4 unicast destination
address prefix and on the forwarding next-hop address.

Bundle VLAN sessions are restricted to an interval of 250
milliseconds and a multiplier of 3. More aggressive
parameters are not allowed.
