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.

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