For my own education, why blackhole the route rather than simply not propagate it at all to the FIB (i.e. ignore it)? Is the aim here to avoid the consequent ICMP unreachable packets closing TCP sessions during reconvergence? How should the blackhole route interact with other routing protocols? -- Alex Bligh
