Hello Chamakura,
your configurations look like correct, inter-vlan routing is performed by C3750, packets can go up and down the trunk uplink in different vlans.
Verify that all vlans are defined at layer2 on both switches if you are not using vtp.
Hope to help

Hi Chamakura,
Look like your configuration is fine, just do the following:
#1 On 2950 Switch Prompt, do ping all VLAN IP Address
VLAN 2 - 192.168.2.254
VLAN 3 - 192.168.3.254
VLAN 4 - 192.168.4.254
VLAN 5 - 192.168.5.254
Just add 192.168.3.0 (VLAN 3) network in your RIP protocol if you want it to advertise.
#2 If ping is not successful, please double check your config, if ping is successful, proceed to #3
#3. On 2950-Switch - VLAN 2, all PC/devices connected to this switch must used ip address belong to 192.168.2.0/24 (VLAN 2 - I said these because all port of this switch is member of VLAN 2) with a default gateway of 192.168.2.254 (VLAN 2 IP Address). Same goes to other devices connected to other VLAN.

Hi Kiran,
Hmm, I'm just wondering if you already check your Computer-A for any installed firewall software. Might be a firewall feature in ur Computer-A preventing Computer-B to establish a ping.
