Example of Setting Up Five VRFs
In this procedure you will add four non-default VRFs to the existing default VRF. This procedure assumes that the following
interfaces are using these IP addresses:
Type
Interface
Address/subnet
GigE
17/1.0
10.0.0.1/24
GigE
17/1.1
20.0.0.1/24
GigE
17/1.2
30.0.0.1/24
GigE
18/1.1
40.0.0.1/24
GigE
18/1.2
50.0.0.1/24
Cable-mac
1
110.0.0.1/24
Cable-mac
2
120.0.0.1/24
Cable-mac
3
130.0.0.1/24
Cable-mac
4
140.0.0.1/24
Cable-mac
5
150.0.0.1/24
1.
These are the commands you would use to define the interfaces listed above:
configure interface gigabitEthernet 17/1.0 ip address 10.0.0.1 255.255.255.0
configure interface gigabitEthernet 17/1.1 ip address 20.0.0.1 255.255.255.0
configure interface gigabitEthernet 17/1.2 ip address 30.0.0.1 255.255.255.0
configure interface gigabitEthernet 18/1.1 ip address 40.0.0.1 255.255.255.0
configure interface gigabitEthernet 18/1.2 ip address 50.0.0.1 255.255.255.0
configure interface cable-mac 1 ip address 110.0.0.1 255.255.255.0
configure interface cable-mac 2 ip address 120.0.0.1 255.255.255.0
configure interface cable-mac 3 ip address 130.0.0.1 255.255.255.0
configure interface cable-mac 4 ip address 140.0.0.1 255.255.255.0
configure interface cable-mac 5 ip address 150.0.0.1 255.255.255.0
2.
Create the VRFs:
configure ip vrf vrf1
configure ip vrf vrf2
configure ip vrf vrf3
configure ip vrf vrf4
3.
The purpose of this step is to associate the interfaces with VRFs.
configure interface gigabitEthernet 17/1.0 ip vrf forwarding default
configure interface gigabitEthernet 17/1.1 ip vrf forwarding vrf1
configure interface gigabitEthernet 17/1.2 ip vrf forwarding vrf2
configure interface gigabitEthernet 18/1.1 ip vrf forwarding vrf3
configure interface gigabitEthernet 18/1.2 ip vrf forwarding vrf4
configure interface cable-mac 1 ip vrf forwarding default
configure interface cable-mac 2 ip vrf forwarding vrf1
configure interface cable-mac 3 ip vrf forwarding vrf2
