Hi Ewan, You mentioned that these interfaces are ‘bridged to the same host phy interface’ – can you please share the relevant configs for that.

Why we process like this on version 17.04. version 16.09 if ((!((FIB_ENTRY_FLAG_ATTACHED & src_flags) || (FIB_ENTRY_FLAG_CONNECTED & src_flags)) || sw_if_index0 != fib_entry_get_resolving_interface (src_fei)) ) { error0 = ETHERNET_ARP_ERROR_l3_src_address_not_local; goto drop2; } version 17.04 if (!((FIB_ENTRY_FLAG_ATTACHED & src_flags) || (FIB_ENTRY_FLAG_CONNECTED & src_flags)) ) { error0 = ETHERNET_ARP_ERROR_l3_src_address_not_local; goto drop2; } Regards, Ewan ________________________________ [email protected]
