I all we are going to terminate point to point link between 3750 and 6506.
on 6506
int gi1/45
no switchport access
ip address 192.X.0.x 255.255.255.0
no shut
routes
ip route 172.16.X.0 255.255.255.0 192.168.0.53
172.16.200.1 is the vlan created on 3750
on 3750 stack switch
int gi1/01
no switchport
ip address 192.X.0.x 255.255.255.0
no shut
ip route 0.0.0.0 0.0.0.0 192.168.0.54
vlan created
int vlan 220
ip address 172.16.X.1 255.255.255.0
Does this config correct as i am configuring between stack switch and 6506
