Simple question:
Will a 6509 still route traffic between connected vlans ( with interfaces and addresses assigned ) without the "ip routing" command in it's configuration?

IP Routing on a C6500 it is enabled by default, and it is also enabled on your C6500.

Hi,
no this will not work.
When you disable routing you turn your C6500 into a bridge. In fact, you won't be able to have more than 1 L3 interface active.

Reason I asked is that I have a 6509 with 7 vlans. Each VLAN has a VLAN interface configured with an IP address assigned. Traffic flows between VLANs with no problem. The 6509 configuration does not include the "ip routing" command. The following is from my 6509. I trimmed unneccessary details to keep it small.

what do you get if you do a "show ip route"?
02-16-2010 06:09 AM
I see connected subnets and static routes for other subnets.
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route
Gateway of last resort is 10.6.23.10 to network 0.0.0.0
204.187.87.0/32 is subnetted, 1 subnets
S 204.187.87.33 [1/0] via 10.6.24.201
S 81.255.165.0/24 [1/0] via 10.6.23.10
S 81.255.170.41/32 [1/0] via 10.6.23.10
S 81.255.165.149/32 [1/0] via 10.6.23.10
10.0.0.0/8 is variably subnetted, 30 subnets, 5 masks
S 10.26.16.0/20 [1/0] via 10.6.23.10
C 10.10.4.0/22 is directly connected, Vlan40

Hi,
Routing is enabled on your C6500. It is not in the config because it is enabled by default.
HTH,
Dario

I 'm not sure that routing is enabled by default. The 6509 (w/msfc2) has MLS enabled. With Multilayer switching enabled, it will "switch" layer 3 traffic. Sort of like routing, only it appears to have some limitations. But, I wouldn't expect it to allow me to create static routes without routing enabled.
02-16-2010 07:25 AM
IP Routing on a C6500 it is enabled by default, and it is also enabled on your C6500.
02-16-2010 06:21 AM
Then it looks like ip routing is on by default. I expect if you disabled it you would see no ip routing in the configuration, just like you do in a 4500.
