BFD Application Example
Note. The ports will be statically assigned to the router VLANs, as a VLAN must have a physical port
assigned to it in order for the IP router interface to function.
The commands to set up the VLAN configuration are shown below:
Router 1 (using ports 2/1 and 2/2 for the backbone and ports 2/3-5 for end devices):
-> vlan 31
-> ip interface vlan-31 vlan 31 address 31.0.0.1 mask 255.0.0.0
-> vlan 31 port default 2/1
-> vlan 12
-> ip interface vlan-12 vlan 12 address 12.0.0.1 mask 255.0.0.0
-> vlan 12 port default 2/2
-> vlan 10
-> ip interface vlan-10 vlan 10 address 10.0.0.1 mask 255.0.0.0
-> vlan 10 port default 2/3-5
-> ip router router-id 1.1.1.1
These commands created VLANs 31, 12, and 10.
•
VLAN 31 handles the backbone connection from Router 1 to Router 3, using the IP router port 31.0.0.1
and physical port 2/1.
•
VLAN 12 handles the backbone connection from Router 1 to Router 2, using the IP router port 12.0.0.1
and physical port 2/2.
•
VLAN 10 handles the device connections to Router 1, using the IP router port 10.0.0.1 and physical
ports 2/3-5. More ports could be added at a later time if necessary.
The router was assigned the Router ID of 1.1.1.1.
Router 2 (using ports 2/1 and 2/2 for the backbone and ports 2/3-5 for end devices):
-> vlan 12
-> ip interface vlan-12 vlan 12 address 12.0.0.2 mask 255.0.0.0
-> vlan 12 port default 2/1
-> vlan 23
-> ip interface vlan-23 vlan 23 address 23.0.0.2 mask 255.0.0.0
-> vlan 23 port default 2/2
-> vlan 20
-> ip interface vlan-20 vlan 20 address 20.0.0.2 mask 255.0.0.0
-> vlan 20 port default 2/3-5
-> ip router router-id 2.2.2.2
These commands created VLANs 12, 23, and 20.
•
VLAN 12 handles the backbone connection from Router 1 to Router 2, using the IP router port 12.0.0.2
and physical port 2/1.
•
VLAN 23 handles the backbone connection from Router 2 to Router 3, using the IP router port 23.0.0.2
and physical port 2/2.
