FIGURE 74 EBGP to CE network example
To configure EBGP to exchange routes between PE routers and CE routers, the user must perform
the configuration steps listed below.
1. “Configuring EBGP on a CE router” .
2. “Configuring EBGP on a PE router” .
Configuring EBGP on a CE router
To allow route exchange between a CE router and its associated PE router, BGP must be enabled on
the CE router and the associated PE router must be configured as a BGP neighbor. To enable BGP
on CE 1 and assign PE 1 as a BGP neighbor in the network shown in
Figure 74 , enter the following
commands.
Brocade(config)# router bgp
Brocade(config-bgp)# local-as 2
Brocade(config-bgp)# neighbor 10.33.33.3 remote-as 1
Configuring EBGP on a PE router
To allow route exchange between a VRF on a PE router and its associated CE router, BGP must be
enabled on the appropriate VRF of the PE router and the associated CE router must be configured
as a BGP neighbor. To assign CE 1 as a BGP neighbor to the VRF VPN1 on PE 1 in the network
shown in
Figure 74 , enter the following commands.
Brocade(config-bgp)# address-family ipv4 unicast vrf VPN1
Brocade(config-bgp-ipv4u-vrf)# neighbor 10.33.33.2 remote-as 2
