30 BGP null0 routing Configuration examples S6 The following configuration defines specific prefixes to filter. PowerConnect(config)#ip route 110.0.0.40/29 ethernet 3/7 tag 50 PowerConnect(config)#ip route 115.0.0.192/27 ethernet 3/7 tag 50 PowerConnect(config)#ip route 120.014.0/23 ethernet 3/7 tag 50 The following configuration redistributes routes into BGP. PowerConnect(config)#router bgp PowerConnect(config-bgp-router)#local-as 100 PowerConnect(config-bgp-router)#neighbor remote-as 100 PowerConnect(config-bgp-router)#neighbor remote-as 100 PowerConnect(config-bgp-router)#neighbor remote-as 100 PowerConnect(config-bgp-router)#neighbor remote-as 100 PowerConnect(config-bgp-router)#neighbor remote-as 100 PowerConnect(config-bgp-router)#neighbor remote-as 100 PowerConnect(config-bgp-router)#redistribute static route-map blockuser PowerConnect(config-bgp-router)#exit The following configuration defines the specific next hop address and sets the local preference to preferred. PowerConnect(config)#route-map blockuser permit 10 PowerConnect(config-routemap blockuser)#match tag 50 PowerConnect(config-routemap blockuser)#set ip next-hop 199.199.1.1 PowerConnect(config-routemap blockuser)#set local-preference 1000000 PowerConnect(config-routemap blockuser)#set origin igp PowerConnect(config-routemap blockuser)#exit S1 The following configuration defines the null0 route to the specific next hop address.

BGP null0 routing

Configuration examples

The following configuration defines specific prefixes to filter.

PowerConnect(config)#ip route 110.0.0.40/29 ethernet 3/7 tag 50

PowerConnect(config)#ip route 115.0.0.192/27 ethernet 3/7 tag 50

PowerConnect(config)#ip route 120.014.0/23 ethernet 3/7 tag 50

The following configuration redistributes routes into BGP.

PowerConnect(config)#router bgp

PowerConnect(config-bgp-router)#local-as 100

PowerConnect(config-bgp-router)#neighbor <router1_int_ip address> remote-as 100

PowerConnect(config-bgp-router)#neighbor <router2_int_ip address> remote-as 100

PowerConnect(config-bgp-router)#neighbor <router3_int_ip address> remote-as 100

PowerConnect(config-bgp-router)#neighbor <router4_int_ip address> remote-as 100

PowerConnect(config-bgp-router)#neighbor <router5_int_ip address> remote-as 100

PowerConnect(config-bgp-router)#neighbor <router7_int_ip address> remote-as 100

PowerConnect(config-bgp-router)#redistribute static route-map blockuser

PowerConnect(config-bgp-router)#exit

The following configuration defines the specific next hop address and sets the local preference to

preferred.

PowerConnect(config)#route-map blockuser permit 10

PowerConnect(config-routemap blockuser)#match tag 50

PowerConnect(config-routemap blockuser)#set ip next-hop 199.199.1.1

PowerConnect(config-routemap blockuser)#set local-preference 1000000

PowerConnect(config-routemap blockuser)#set origin igp

PowerConnect(config-routemap blockuser)#exit

The following configuration defines the null0 route to the specific next hop address. The next hop

address 199.199.1.1 points to the null0 route.

PowerConnect(config)#ip route 199.199.1.1/32 null0

PowerConnect(config)#router bgp

PowerConnect(config-bgp-router)#local-as 100

PowerConnect(config-bgp-router)#neighbor <router2_int_ip address> remote-as 100

PowerConnect(config-bgp-router)#neighbor <router3_int_ip address> remote-as 100

PowerConnect(config-bgp-router)#neighbor <router4_int_ip address> remote-as 100

PowerConnect(config-bgp-router)#neighbor <router5_int_ip address> remote-as 100

PowerConnect(config-bgp-router)#neighbor <router6_int_ip address> remote-as 100

PowerConnect(config-bgp-router)#neighbor <router7_int_ip address> remote-as 100

The following configuration defines a null0 route to the specific next hop address. The next hop

address 199.199.1.1 points to the null0 route, which gets blocked.

PowerConnect(config)#ip route 199.199.1.1/32 null0

PowerConnect(config)#router bgp

PowerConnect(config-bgp-router)#local-as 100

PowerConnect(config-bgp-router)#neighbor <router1_int_ip address> remote-as 100

PowerConnect(config-bgp-router)#neighbor <router3_int_ip address> remote-as 100

PowerConnect(config-bgp-router)#neighbor <router4_int_ip address> remote-as 100

PowerConnect (config-bgp-router)#neighbor <router5_int_ip address> remote-as 100

PowerConnect(config-bgp-router)#neighbor <router6_int_ip address> remote-as 100

PowerConnect(config-bgp-router)#neighbor <router7_int_ip address> remote-as 100
