I get the following error "arpresolve: can't allocate llinfo for 1.1.245.19= 2 on vlan320" I can't explain. (IP edited). I only setup 1.1.245.192/31 bet= ween this vlan which parent is a VF from a MLX5EN(4) card . I am using a generated mac address and distribute IPs over OSPF with bird.= =20 What could trigger this error? The doc says ``` .It "arpresolve: can't allocate llinfo for %d.%d.%d.%d" The route for the referenced host points to a device upon which ARP is required, but ARP was unable to allocate a routing table entry in which to store the host's MAC address. This usually points to a misconfigured routing table. It can also occur if the kernel cannot allocate memory. ``` But I am not sure what to check. Any hint is welcome :) The configuration for this vlan is locally: ``` vlan320: flags=3D1008843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST,LOWER_UP> m= etric 0 mtu 1500options=3D1c680703<RXCSUM,TXCSUM,TSO4,TSO6,LRO,LINKSTATE,RX= CSUM_IPV6,TXCSUM_IPV6,MEXTPG,TXTLS4,TXTLS6> ether 02:01:02:01:01:01 inet 1.1245.193 netmask 0xfffffffe broadcast 255.255.255.255 inet6 fe80::1:2ff:fe01:101%vlan320 prefixlen 64 scopeid 0x9 inet6 XXXX:XXXX:1:fe02::2 prefixlen 64 groups: vlan vlan: 320 vlanproto: 802.1q vlanpcp: 0 parent interface: mce1 media: Ethernet 25GBase-SR <full-duplex,rxpause,txpause> status: active nd6 options=3D21<PERFORMNUD,AUTO_LINKLOCAL> ``` vlan320: flags=3D1008843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST,LOWER_UP> m= etric 0 mtu 1500 =09options=3D1c680703<RXCSUM,TXCSUM,TSO4,TSO6,LRO,LINKSTATE,RXCSUM_IPV6,TXC= SUM_IPV6,MEXTPG,TXTLS4,TXTLS6> =09ether 02:01:02:02:01:01 =09inet 1.1.245.192 netmask 0xfffffffe broadcast 255.255.255.255 =09inet6 fe80::1:2ff:fe02:101%vlan320 prefixlen 64 scopeid 0xa =09groups: vlan =09vlan: 320 vlanproto: 802.1q vlanpcp: 0 parent interface: mce1 =09media: Ethernet 25GBase-SR <full-duplex,rxpause,txpause> =09status: active =09nd6 options=3D21<PERFORMNUD,AUTO_LINKLOCAL> ``` on remote: ``` Beno=C3=AEt
