BGP or MPLS VPN sample configurations

Brocade(config)# interface loopback 1

Brocade(config-lbif-1)# ip address 10.33.33.1/32

Brocade(config-lbif-1)# exit

Brocade(config)# ip route 10.1.2.0/24 10.33.33.1

Brocade(config)# router ospf

Brocade(config-ospf-router)# area 1

Brocade(config-ospf-router)# redistribute static

Brocade(config-ospf-router)# exit

Brocade(config)# interface ethernet 1/1

Brocade(config-if-e10000-1/1)# ip address 10.33.33.2

Brocade(config-if-e10000-1/1)# ip ospf area 1

Brocade(config-if-e10000-1/1)# exit

CE 5 configuration

This configuration example describes what is required to operate the CE 5 router in Figure 77. In

this example, a static route is configured between the external network (10.1.3.0/24) and the

loopback interface. OSPF is configured to redistribute static routes between the CE 5 router and

the attached interface of PE 4.

Brocade(config)# interface loopback 1

Brocade(config-lbif-1)# ip address 10.33.36.1/32

Brocade(config-lbif-1)# exit

Brocade(config)# ip route 10.1.3.0/24 10.33.36.1

Brocade(config)# router ospf

Brocade(config-ospf-router)# area 1

Brocade(config-ospf-router)# redistribution static

Brocade(config-ospf-router)# exit

Brocade(config)# interface ethernet 1/1

Brocade(config-if-e10000-1/1)# ip address 10.33.36.2

Brocade(config-if-e10000-1/1)# ip ospf area 1

Brocade(config-if-e10000-1/1)# exit

PE 1 configuration

This configuration example describes what is required to operate the PE 1 router in Figure 77. In

this example, the VRF VPN1 is created with a unique route descriptor consisting of the BGP AS

number (1) and a random other number (2), and route targets are set for import and export. The

VRF (VPN1) is defined on the interface that connects to CE 1. OSPF is configured on the VRF

named VPN1 to exchange routes with CE 1 and to redistribute routes from across the MPLS

domain.

IBGP with extended community attributes is configured between PE 1 and PE 4. The OSPF area is

specified as 0 and MPLS is set up for OSPF traffic engineering. In addition, MPLS is configured with

a signalled LSP named “tunnel1” to PE 1.

Brocade(config)# interface loopback 1

Brocade(config-lbif-1)# ip address 10.2.2.1/24

Brocade(config-lbif-1)# ip ospf area 0

Brocade(config-lbif-1)# exit

Brocade(config)# vrf VPN1

Brocade(config-vrf-vpn1)# rd 1:1

Brocade(config-vrf-vpn1)# route-target export 100:1
