Configuring Multi-VRF

Brocade(config)# router ospf

Brocade(config-ospf-router)# area 0

Brocade(config-ospf-router)# redistribution connected

Brocade(config-ospf-router)# exit

Brocade(config)# interface loopback 1

Brocade(config-lbif-1)# ip address 10.1.2.1/32

Brocade(config-lbif-1)# ip address 10.1.3.1/32

Brocade(config-lbif-1)# interface ethernet 1/1

Brocade(config-if-e1000-1/1)# ip ospf area 0

Brocade(config-if-e1000-1/1)# ip address 10.1.1.2/24

CE 3 and CE 4 configurations

The CE3 and CE4 router configurations are exactly the same. Both are configured in OSPF Area 0
with route redistribution enabled. The IP addresses: 10.2.2.1/32 and 10.2.3.1/32 are configured
for the Loopback1 interface allowing them to carry routes from these networks.

Brocade(config)# router ospf

Brocade(config-ospf-router)# area 0

Brocade(config-ospf-router)# redistribution connected

Brocade(config-ospf-router)# exit

Brocade(config)# interface loopback 1

Brocade(config-lbif-1)# ip address 10.2.2.1/32

Brocade(config-lbif-1)# ip address 10.2.3.1/32

Brocade(config-lbif-1)# interface ethernet 1/1

Brocade(config-if-e1000-1/1)# ip ospf area 0

Brocade(config-if-e1000-1/1)# ip address 10.2.1.2/24

Configuration 2

As shown in

Figure 28

, OSPF (Area 0) is configured between PE1 and PE2 and OSPF (Area 1 and

Area 2) is configured between PEs and CEs. The biggest difference between this configuration and
Configuration 1 is that OSPF is used between the 2 PEs instead of eBGP. Otherwise most of the
configuration is the same as Configuration 1.
