EIGRP is running across the core to exchange internal routes, and each router maintains iBGP adjacency with the other routers on the network. An operator has configured static routes on the edge routers R1 and R2 for IP address 10.0.1.1, which is used as a black hole route as shown. Which configuration should the operator implement to the management router to create a route map that will redistribute tagged static routes into BGP and create a static route to blackhole traffic with tag 777 that is destined to the server at 192.168.10.100?

router(config)# route-map blackhole-trigger
router(config-route-map)# match tag 777
router(config-route-map)# set ip next-hop 10.0.1.1
router(config-route-map)# set origin igp
router{config-route-map)# set community no-export

  • A. router(config)# router bgp 55100
    router(config-router)# redistribute static route-map blackhole-trigger
    router(config)# ip route 10.0.1.1 255.255.255.255 Null0 tag 777
  • B. router(config)# router bgp 55100
    router(config-router)# redistribute static route-map blackhole-trigger
    router(config)# ip route 192.168.10.100 255.255.255.255 Null0 tag 777
  • C. router(config)# router bgp 55100
    router(config-router)# redistribute connected
    router(config)# ip route 192.168.10.100 255.255.255.255 tag 777
  • D. router(config)# router bgp 55100
    router(config-router)# redistribute connected route-map blackhole-trigger
    router(config)# ip route 192.168.10.100 255.255.255.255 Null0 tag 777
