router 2691 with NM-16ESW module

[sarahr202]

Hi everybody

I am trying to perform this lab where i need a layer 3 switch.  I am using gns3.   I  am trying to use  router 2691with NM-16ESW module as a layer 3 switch.

h2-----vlan1--f1/1( router 2691) f1/2---vlan2-------h3

(remember in above set up, router 2691 is being used as layer 3 switch; only ports off module NM-6ESW are connected to hosts: h2 and h3)

h2 199.199.199.2

h3 193.193.193.3

Where f1/1  and f1/1 are  located on NM-16 ESW module.

Router 2691 config:

int f1/1

switchport access vlan 1

int f1/2

switchport access vlan 2

int vlan 1

ip address 199.199.199.1/24

int vlan 2

193.193.193.1/2

=====================

When i send ping packets from h1to 19.193.193.3 ( i.e h3), they are dropped.  what am i missing?

Is  something wrong with my con?

I will really appreciate any help .

thanks and have a nice weekend.

Hi Sarah,

The switch module is layer-2 only.  If you have multiple interfaces with multiple vlans, you need to configure the router itself (2691) with sub-interface and .1q for each vlan.  This way the switch performs layer-2 and the router routes between the subnets.

Have a nice weekend

   This might help . Did you create the vlans in the vlan database ?
