ARP hardware address incomplete!

[san ju.]

Hi there,

When I take ARP details for an IP, it shows "Incomplete".  

Protocol     Address            Age (min)         Hardware Addr       Type       Interface
Internet      23.148.3.61                0            Incomplete           ARPA

Your assistance would be greatly appreciated  !!!

Hi,

normally when cisco device generate ARP, its adding 'incomplete' record ARP table. once it received the correct MAC, it updates the table. if it nor received the MAC until expire timer hit, then record will be delete from ARP table.

rate this and mark as a answer if it resolved your concern

Hello

From that device an arp request has beed sent for that host but it hasnt replied, check to make sure the host is active and has the correct addressing assigned.

Hi All,

thanks for the replay,

Pinging to 23.148.3.61 working fine after I created a VLAN subinterface"6.555" on the router and allocated 23.148.3.5, but now I allocated an IP in G2 on router "23.148.3.2/24" (carrier link of the router) it's overlapping!!! - and this G2 must be up(redundancy protocol is applied on this interface) so I deleted the IP on the "6.555" subinterfaces.

My main goal is to make Ping to "23.148.3.61" it's a WIN server IP!!!!

interface GigabitEthernet4
description ***PUBLIC_LAN1***
ip address 23.148.3.2 255.255.255.0


interface GigabitEthernet6.555
encapsulation dot1Q 503
end

so how I can get ping to the "23.148.3.61"?

Your assistance would be greatly appreciated  !!!

Hello
23.148.3.2/24 < -- gig0/4
23.148.3.61/24 ---gig6.555 (not applicable)

If 23.148.3.0/24 is being used on a routed interface already you cannot use any ip address with that range for another interface as it will overlap.

The below example will work however you NEED to make sure you understand your own ip address management before you start allocating ip addressing?

23.148.3.0/30 < -- gig0/4 (host 1 & 2)
23.148.3.60/30 ---gig6.555 (applicable) (host 61 & 62)
