When implementing source-based remote-triggered black hole filtering, which two configurations
are required on the edge routers that are not the signaling router? (Choose two.)
A.
A static route to a prefix that is not used in the network with a next hop set to the Null0 interface
B.
A static route pointing to the IP address of the attacker
C.
uRPF on all external facing interfaces at the edge routers
D.
Redistribution into BGP of the static route that points to the IP address of the attacker
E.
A route policy to set the redistributed static routes with the no-export BGP community
