Dear All,
I had a nW of lasrge no of devices and 50 Vlans + 4 Routers.
Problem is from the site in all segment some the IPs can not comunicate out side the campus NW. When I released the IP and Renewed the IP it will works with the same IP as before.
But the problem is yet persits PCs wirth staic IP as cann't release or renew IP.
Can anyone suggest me what could be the probable reason and solution ?
I m pasting the tracert before IP release Renew.

Today for static or DHCP IPs all have problem can be resolved by pinging all MSFCs HSRP IP address or from MSFCs tp PC iP address the problem has been resolved.
Can any one suugest the solution.

are you using dynamic routing?

Hi,
You can troubleshoot your issue by resuming the IP route command in every step of the routing paths in the failing tracert.
Good bye

Problem is not in whole segment so I think problem is not dueto Routing but there may due to ARP issue but yet I can't find the solution. Yet Problem is there but it's working by giveing the solution of ping from PC to MSFC or MSFC to PC.

Yes . Intervlan Routing is done by L3 Switch and WAN Routing is done by OSPF.
And the problem is not in whole segment. It's in some of the IPs only. Today I have found that it may ARP related problem. because if I ping from Pc to MSFC or MSFC tp PC IP than All are working again.

Try to clear the ARP table :
Clear ARP Table of your Cisco router or switch
To clear the ARP table, in enable mode:
Router#clear arp
Show ARP table of a Cisco router or switch
To display the ARP table of a Cisco router, in enable mode:
Router#show arp

dear yassine-m,
I have cleared arp from both the MSFCs. but the problem remain present finally I had rebooted one of the Core switch.
ow confusion is that problem is also in the segment those are not active from this core.
And after rebooting problem is resolved.
