here i used the recommendations of making the DHCP server an external server and just use the command IP helper X.X.X.X in cisco 4500X under each interface vlan to relay DHCP to hosts in this vlan , so that i can get IP on the host machine but when i try to ping machine in other vlan which also obtain its ip from this DHCP server , ping is time out . when i disable ip helper command and make my core switch as DHCP server for each vlan ,inter-vlan routing work probably and i could ping remote host in other vlans .
note i did same configuration on the DR site on cisco 4506 core switch and it's work probably.

This is the Jabber Clients community, you probably want to move this a switching/routing community.

Hi Ahmed,
This sounds like a default gateway isue.
When the DHCP is on the external server
What is the default gateway you have set
in the pool/scope for the client ?
Is that reachable from other vlans ?
May be you could supply the full network addressing details etc
of what you are trying to achieve.
Regards
Alex
