BFD on Bundle Member Links: Examples
The following example shows how to configure BFD on member links of Ethernet bundle interfaces:
bfd
interface Bundle-Ether4
echo disable
!
interface GigabitEthernet0/0/0/2.3
echo disable
!
!
interface GigabitEthernet0/0/0/3 bundle id 1 mode active
interface GigabitEthernet0/0/0/4 bundle id 2 mode active
interface GigabitEthernet0/1/0/2 bundle id 3 mode active
interface GigabitEthernet0/1/0/3 bundle id 4 mode active
interface Bundle-Ether1
ipv4 address 192.168.1.1/30
bundle minimum-active links 1
!
interface Bundle-Ether1.1
ipv4 address 192.168.100.1/30
encapsulation dot1q 1001
