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_entry_t *fib_entry, u8*s); -extern u8* fib_ae_export_format(fib_entry_t *fib_entry, u8*s); - -#endif |
