derived from. For example, in Figure 78 the routes that are admitted into VPN1 and VPN2 have
route targets of 1:1 and 2:2. The user can use the cooperative route filtering feature to send an
ORF that is derived from the route-target import commands on PE 1 to PE 2 to only accept these
routes.
FIGURE 78 Cooperative route filtering example
The following example shows the commands required to configure VRF VPN1 on PE 1 in Figure 78
with an import route-target of 1:1 and VRF VPN2 on PE 1 with an import route-target import of 2:2.
Brocade(config)# vrf VPN1
Brocade(config-vrf-VPN1)# route-target import 1:1
Brocade(config-vrf-VPN1)# exit-vrf
Brocade(config)# vrf VPN2
Brocade(config-vrf-VPN2)# route-target import 2:2
Brocade(config-vrf-VPN2)# exit-vrf
The following commands configure PE 1 to send the filter derived from the import route-target
commands in VPN1 and VPN2 to PE 2.
Brocade(config-bgp)# address-family vpnv4 unicast
Brocade(config-bgp-vpnv4u)# neighbor 10.3.3.2 capability orf extended-community
send-vrf-filter
The following commands configure PE 2 to receive the filter derived from the import route-target
commands in VPN1 and VPN2 on PE 1.
Brocade(config-bgp)# address-family vpnv4 unicast
Brocade(config-bgp-ivpnv4u)# neighbor 10.3.3.1 capability orf extended-community
