Hi
as long as the service provider router has route back to both subnets this should work fine

Thanks mahmood but prob is internal vlan are subnetted and service provider inward route doesnt cover whole range and i still can ping all device in both range....may be its finding route based on longest match

int vlanx

ip add 10.x.x.4 255.255.255.128

int vlan y

ip add 10.x.x.129 255.255.255.128

service proivder route

S 10.x.x.0/25 via gig 0/1   ( service proivder router pointing internally not covering full range should be /24 unless looking for route and choosing one on longest match
