Configuring Multi-VRF
FIGURE 28 OSPF (Area 0) configured between PE1 and PE2 with OSPF (Area 1 and Area 2)
configured between PEs and CEs
The following configuration examples for PE1, PE2, CE1, CE2, CE3, and CE4 describe how to create
the example shown in Figure 28.
PE1 configuration:
In this configuration, VLANs 10 and 20 are created as a link on a tagged port (e 1/10) between PE1
and PE2. Two VRFs (“RED” and “GREEN”) are then defined with each having a unique Route
Distinguisher (RD). VRF “Green” is assigned an RD value of 10:10, and VRF “Red” is assigned an
RD value of 20:20.
Because OSPF is the only routing protocol used in this set-up, multiple OSPF areas are used. Area 0
is configured between the two PEs. Area 1 is configured PE1 and CE’s 1 and 2. Area 0 is configured
between the two PEs. Area 2 is configured PE2 and CE’s 3 and 4.
The virtual Interfaces (ve10 and ve20) are configured with the same IP address (10.3.1.1/24) and
for VRF forwarding in the appropriate VRF (Green or Red). Both are also configured in OSPF Area 0.
