Use Single Cisco L3 switch (3750) as a router and configure 2 ISPs

Level 1

I need to use Single Cisco L3 switch (3750) as a router and configure 2 ISPs with static routes to connect to internet.

I don't want any load balancing or Failover, just route the traffic separately on both ISP and no inter vLAN routing.

I want to leverage the /29 LAN IP pool provided by ISPs, help me with routing.

configuration:

interface GigabitEthernet0/1      

no switchport

ip address 215.214.125.254 255.255.255.252       ---------------  ISP1 WAN Gateway

duplex auto

speed auto

!

interface GigabitEthernet0/2

no switchport

ip address 102.172.125.254 255.255.255.252  --------------ISP2 WAN Gateway

duplex auto

speed auto

!

interface Vlan1

description ISP1 LAN 

ip address 215.120.248.9 255.255.255.248                  --------------  Default gate way for LAN pool of ISP1

!

interface Vlan2

description ISP2 LAN 

mac-address 00d0.bae8.1c01

ip address 82.18.40.41 255.255.255.248                             --------------  Default gate way for LAN pool of ISP2
