help with configuring L3 on cisco cat 6506

[tonyam98]

trying to setup in a test environment on a 6506 l3 between vlan 2 10.20.2.0 /24 and vlan 3 10.20.3.0 /24

this what i did

session 15

int vlan 2

ip address 10.20.2.254 255.255.255.0

no shut

int vlan 3

ip address 10.20.3.254 255.255.255.0

no shut

router igrp 100

network 10.0.0.0

What is missing ?

ip routing

since it is one switch should i still set up spanning tree in switch module?

[amitbatra]

which supervisor engine are u using. bcoz in sup 720 we need not to give ip routing. by default it is enabled.but in switches like 3550 we have to give this command. one thing more i waana know before giving u any solution is that have created vlan's in vlan database. coz generally people forget that.

It looks ok from what I can tell , why do you think it isn't working ? Also without seeing the layer 2 side and knowing what is connected behind that it's difficult to say .

[tonyam98]

I did the following:

switch module:

set vlan 2 3/13-24

set vlan 3 3/25-36

set vlan 4 3/37-48

set interface sc0 2 10.20.2.4 255.255.255.0

I did not set ip route default xxxxx

set port speed 3/1 10

set port speed 3/2-48 100

set port duplex full

I'm not in front of the switch at this time but the ip route showed C for 10.20.3.0 10.20.3.0 networks

I then configured one host in the vlan 2 with 10.20.2.177 /24 gw 10.20.2.254

another in vlan 3 with 10.20.3.20 /24 gw 10.20.3.254

try using eigrp instead of IGRP maybe it has something to do with IGRP being classfull as opposed to eigrp which is classless.

Since your Vlans are connected on the MSFC you need not have any routing protocol ..ip routing is enough .u caan remove routing protocol and check sh ip route if you can see two subnets.

Moreover please check onyour sup engine can you see both vlans active ??? sh vlan. moreover can users in vlan 2 and vlan 3 ping their default GW ?

Thanks for the input... I think I misconfigured a host on one vlan...everything is working fine.
