WAN & LAN configuration on L3 Switch

[ravikirans6761]

ISP has given two blocks of IPs. i.e WAN(/30) & LAN(/29). Right now i have only L3 switch. How do I configure WAN and LAN IP on layer 3 switch?

can anyone help me plz...!

Could you tell us which layer 3 switch you have?

The basic jist - interface that the ISP plugs into:

interface Gigabit a/b
  no switch port
  ip address a.b.c.d 255.255.255.252
ip route 0.0.0.0 0.0.0.0 <ISP IP address>

Configure a VLAN for your servers:

interface VLAN50
  ip address a.b.c.d 255.255.255.248

And put a port into that vlan:

interface Gigabit a/b
  switch mode access
  switchport access vlan 50

Thanks Mr. Philip for your response.

I have been working in wireless domain since last 4 years. 

Now planning to change my carrier path from wireless to routing&switching. I have already started preparation for CCNA and CCNP exams.

could you please give any suggestions and where can i download DUMPs for preparation ?

Thanks in advance.

I don't know what DUMPs is.  If you have a modern computer with 4 CPU cores or better and 8GB or more of RAM then Cisco VIRL is pretty good.
