Clearly out of * Ggi0. It's an attached route, hence we are saying that we can ARP for * hosts in the attached subnet. and we can. but any ARP entries we send * we be received on Gig0, but since Gig0 is in table 2, it will install * the adj-fins in table 2. So traffic in table 3 will never hit an adj-fib * and hence always the glean, and so thus be effectively dropped. * How do we fix this? Attached Export !! All more specfiic entries in table 2 * that track and are covered by the connected are automatically exported into * table 3. Now table 3 also has adj-fibs (and the local) so traffic to hosts * is restored. */ #ifndef __FIB_ATTACHED_EXPORT_H__ #define __FIB_ATTACHED_EXPORT_H__ #include <vnet/fib/fib_types.h> extern void fib_attached_export_import(fib_entry_t *fib_entry, fib_node_index_t export_fib); extern void fib_attached_export_purge(fib_entry_t *fib_entry); extern void fib_attached_export_covered_added(fib_entry_t *cover, fib_node_index_t covered); extern void fib_attached_export_covered_removed(fib_entry_t *cover, fib_node_index_t covered); extern void fib_attached_export_cover_change(fib_entry_t *fib_entry); extern void fib_attached_export_cover_update(fib_entry_t *fib_entry); extern u8* fib_ae_import_format(fib_node_index_t impi, u8*s); extern u8* fib_ae_export_format(fib_node_index_t expi, u8*s); #endif
