Quick question regarding routing between vlans on Ti24

Hi,

I have a Turboiron 24x configured as such:

vlan 101 by port
tagged ethe 7
router-interface ve 101

vlan 998 by port
tagged ethe 19
router-interface ve 2

interface ve 2
ip address 192.168.227.1 255.255.255.248
!
interface ve 101
ip address 192.168.0.1 255.255.255.248

The hosts (192.168.227.2) and (192.168.0.2) can both ping their respective VEs, but they cannot ping one another.

I have static routes nailed up on the hosts:

192.168.0.0 192.168.227.1 255.255.224.0 UG 0 0 0 eth1
And
192.168.227.0 192.168.0.1 255.255.255.0 UG 0 0 0 em2

Anyone know what I need to do to tell it to go ahead and route ?

p.s. the reason the subnets configured on the hosts are larger than what is configured on the TI is because I intend on having multiple subnets reachable in both directions.

Thanks,
-Drew

For basic testing, I would get rid of static host-based routes and use a
default route pointed at the TI24. If that works, then the problem is with
the machines, not the TI.

Re: Quick question regarding routing between vlans on Ti24 [In reply to]

[.Apologies - I Shift-DEL'd the original message before I had a chance to
reply].

Some questions:

1. Are you sure you're using a L3 or L2+ image? What does 'sh version'
output? Since you can configure ve's you probably are but it's worth
checking.

2. What's the output of 'sh ip route'?

3. What's the output of 'sh ip'?

4. Presumably you have no access-list's attached to the interfaces?
