7. Repeat step 3 for all devices interfacing with the Internet (edge corporate devices). In this case, device 2 has the same null0
route as device 1.
8. On device 6, configure the network prefixes associated with the traffic you want to drop. The static route IP address references a
destination address. You must point the static route to the egress port, (for example, Ethernet 1/3/7), and specify the tag 50,
matching the route-map configuration.

Configuration examples

Device 6
The following configuration defines specific prefixes to filter:
device(config)# ip route 10.0.0.40/29 ethernet 1/3/7 tag 50
device(config)# ip route 10.0.0.192/27 ethernet 1/3/7 tag 50
device(config)# ip route 10.014.0/23 ethernet 1/3/7 tag 50
The following configuration redistributes routes into BGP4.
device(config)# router bgp
device(config-bgp-router)# local-as 100
device(config-bgp-router)# neighbor router1_int_ip address remote-as 100
device(config-bgp-router)# neighbor router2_int_ip address remote-as 100
device(config-bgp-router)# neighbor router3_int_ip address remote-as 100
device(config-bgp-router)# neighbor router4_int_ip address remote-as 100
device(config-bgp-router)# neighbor router5_int_ip address remote-as 100
device(config-bgp-router)# neighbor router7_int_ip address remote-as 100
device(config-bgp-router)# redistribute static route-map blockuser
device(config-bgp-router)# exit
The following configuration defines the specific next hop address and sets the local preference to preferred.
device(config)# route-map blockuser permit 10
device(config-routemap blockuser)# match tag 50
device(config-routemap blockuser)# set ip next-hop 10.199.1.1
device(config-routemap blockuser)# set local-preference 1000000
device(config-routemap blockuser)# set origin igp
device(config-routemap blockuser)# exit
NOTE
A match tag can take up to 16 tags. During the execution of a route-map, a match on any tag value in the list is considered a
successful match.
Device 1
The following configuration defines the null0 route to the specific next hop address. The next hop address 10.199.1.1 points to the null0
route.
device(config)# ip route 10.199.1.1/32 null0
device(config)# router bgp
device(config-bgp-router)# local-as 100
device(config-bgp-router)# neighbor router2_int_ip address remote-as 100
device(config-bgp-router)# neighbor router3_int_ip address remote-as 100
device(config-bgp-router)# neighbor router4_int_ip address remote-as 100
device(config-bgp-router)# neighbor router5_int_ip address remote-as 100
device(config-bgp-router)# neighbor router6_int_ip address remote-as 100
device(config-bgp-router)# neighbor router7_int_ip address remote-as 100
