Example: Configuring BFD Hardware-Offload support in a BGP Network
Network
The following example shows how to configure BFD Hardware-Offload support in a BGP network in
Cisco IOS Release 15.1(1)SG. In the following example, the simple BGP network consists of SwitchA
and SwitchB. Gigabit Ethernet interface 6/1 on SwitchA is connected to the same network as Gigabit
Ethernet interface 6/1 in SwitchB.
Configuration for SwitchA
!
interface GigabitEthernet 6/1
no switchport
ip address 1.1.1.1 255.255.255.0
bfd interval 50 min_rx 50 multiplier 3
no bfd echo
router bgp 10
neighbor 1.1.1.2 remote-as 10
neighbor 1.1.1.2 fall-over bfd
!
OL-25340-01
oob-resync timeout 40
Hello due in 00:00:03
Adjacent with neighbor 172.18.0.1
oob-resync timeout 40
Hello due in 00:00:01
