[c-nsp] Bridging two VLANs on Catalyst 6500

[Piff]

Hello,

Few days ago, I tried to ask the following:
> can I bridge two VLANs on a Catalyst 6500 with an external switch?
> The Catalyst is running IOS Version 12.2 (18) SFX.
> The external switch is an Alteon AD.

When the VLANs are bridged I get:

Apr 13 11:27:07: %CDP-4-NATIVE_VLAN_MISMATCH: Native VLAN mismatch discovered on
GigabitEthernet8/1 (10), with router6500 GigabitEthernet8/2 (20).
Apr 13 11:27:19: %CDP-4-NATIVE_VLAN_MISMATCH: Native VLAN mismatch discovered on
GigabitEthernet8/2 (20), with router6500 GigabitEthernet8/1 (10).

Any suggestions?

Thanks,
/P
