GRE Tunnel Routing Problem

Andy,

Ok, let me make sure I get this correct.

Is that 'show run int vlan 333' from the Switch or from R1?

If (interface vlan 333) is from R1, can you post the results from 'show int vlan333' ?

Re: GRE Tunnel Routing Problem

vlan333 is the switch hanging off of the router.

Andy,

Ok, Cool. So on R1, there is a physical port that is connected to this switch. On R1, can you post the results from 'show run int X' where X is the port on Router 1 that is going to this SW.

R1

no ip address

ip flow ingress

Here is the config on the switch that it hooks into as well:

switchport trunk encapsulation dot1q

switchport mode trunk

GRE Tunnel Routing Problem

Andy,

So when it gets to R1, it's going to do a route lookup, and obviously take the default route, since there is no default route.

On Gi0/1, on R1, configure the IP address of 192.168.20.x, X will be some number that you want to use. Once this happens, it will become a directly connected route.

On R1, after you do this, you will see 192.168.20.0 255.255.255.0, and it will ARP out for any host on 192.168.20.x/24.

Is this switch for testing purposes?

Re: GRE Tunnel Routing Problem

Its not for testing purposes but I can play with it a little.  The swtich is a 3560 and routing is not currently enabled on it.  Can I enable routing on the switch and then put a static route on the router?

Ip route 192.168.20.0 255.255.255.0  via 192.168.20.200?

Andy,

We'll, this 3560 switch has an SVI on it, so you should be able to put an IP address on R1 and make it a L3 link basically.

you can try that static route command.

Re: GRE Tunnel Routing Problem

Disregard last post.  I created the interface and it is now routing correctly.  I really appreciate all of your help on this issue.

Thank you very much.
