Routing with a 2650

I am new to routing, so please be kind.

I am using a 2650 and trying to connect a small, private network to our main campus network so clients on the small network can access the internet as well as clients on the large network. I must be missing something as I can't make this work. Here is the configuration:

ip routing
snmp-server community "public" Unrestricted

vlan 1
name "DEFAULT_VLAN"
untagged 1-16,49-50
ip address 143.246.0.81 255.255.128.0
no untagged 17-48
exit

vlan 4
name "test_route"
untagged 31-32
ip address 192.168.50.1 255.255.255.0
exit

ip route 0.0.0.0 0.0.0.0 143.246.0.50
no stack

Any help will be greatly appreciated. Thanks in advance!

Re: Routing with a 2650

Hi

Your scenario is almost complete if :

1- Vlan 1 the port that connects 2650 to the INternet router 143.246.0.50 was untagged to vlan1.

2- You have to add on the Internet router static route to give Vlan4 its way back:
(config)#ip route 192.168.50.1 255.255.255.0 143.246.0.81

In this case you have 2650 with 2 vlans routed between each other, and can access internet.

Now: connecting the 2650 to your Campus network depends on :
- Vlans on campus switches (is vlan4 created there).
- Tagging Vlan4 on uplink ports to campus switches.
- Routing and security on Campus switches.

If you can explain more about your Network map and the problem you are facing, it can help us to sort out your issue.

Good Luck !!!
