"ip routing" not available on CAT 6500?

I was trying to issue a global command "ip routing" to enable inter-VLAN routing on a Cisco 6504 running IOS. But "ip routing" does not seem to be a valid command. Please advise the reason and alternatives.

Re: "ip routing" not available on CAT 6500?

what error message do you get?

Re: "ip routing" not available on CAT 6500?

It says the command "ip routing" does not exist. I am in EXEC mode.

6504#config t

Enter configuration commands, one per line. End with CNTL/Z.

6504(config)#ip routing

% Invalid input detected at '^' marker.

I noticed this the other day when I was setting up a Sup720 in the lab. The issue (if you can call it an issue) is you can't disable IP routing on the 6500 running Native IOS so it is always enabled and can't be disabled. Type 'show ip route' and there will be a routing table (assuming you have at least one interface with an IP address).

turn on Cisco's Express Forwarding (CEF)

- ip cef

then try ip routing?

It may be you can't turn it off so there is no command to turn it on . never really tied to turn it off on the new 720's though we do it all the time on our 4500's.

1. Unless I missed something, I am sure it is running IOS not CatOS.

2. "ip cef" is enabled. It did not solve the issue.

3. Assuming you cannot turn off "ip routing" on, it makes sense because it does show routing tables.

6504#show ip route

C 63.xx.xx.208 is directly connected, Vlan3

S* 0.0.0.0/0 [1/0] via 63.85.41.209

Now the question is how I can enable inter-VLAN routing? I am not able to ping a host on different VLAN. Please advise.

Re: "ip routing" not available on CAT 6500?

If you want to ping from one vlan to the other, make sure that the default gateway on the hosts on these vlans is set to the IP address of their respective vlan interface.

Hope this helps,

Re: "ip routing" not available on CAT 6500?

All host's default gateways are set to the IP address of their respective VLAN interface already. In my case, 172.16.xx.1.
