Enabling a prefix to be hICN will copy all the routes - * in the vrf 0 for the given prefi, in the vrf HICN.

Moreover, we use the lookup in the vrf hICN - * as a way for punting packet that must be processed as hICN. The implementation will - * install a special dpo as a single next hop for the vpp load balancer for each entry - * in the vrf hICN that we enabled. Such dpo will have two purposes: 1) to punt packets - * to the hICN forwarding pipeline, 2) to point to the righe strategy (the dpoi_index will - * be an index to the strategy context while the dpoi_type will be an index to the strategy vft). - * - * Additionally, hICN assign each interface to the vrf hICN; this is required for - * the interest lookup.
