Vlan's convert from IOS version 12.4 to IOS version 15.2
I need some help to get vlan's to get working again.
I have a c2500 with v 12.4 that works with the config above, now with a new c3600 with the smae config but with v15.2 I can't put vlan's working.
I also read about it but I can get it work:
Autonomous AP Will Treat The Sub-interface Tied To Bridge-group1 As The Native Vlan
When using a configuration on an autonomous AP where there is no native VLAN defined, each interface is being dot1q tagged, communication will fail after upgrading to 15.2(2)JA or later. It appears that the configuration is still correct after the upgrade, but the AP sends the untagged frames for bridge-group 1, even though the encapsulation is not defined as native. The autonomous AP will treat the sub-interface tied to bridge-group 1 as the native VLAN, even if it is not defined with the native keyword: "encapsulation dot1 <vlan> native". The VLAN associated with bridge-group 1 must be set to native on the connecting switchport configuration
The workaround for this is to configure VLAN 100 as the native VLAN on the connected switchport trunk, even though the encapsulation is not specified as native on the AP.
IP Routing Enabled By Default
IP routing is enabled by default in 15.2(2)JB. This default configuration will render ip default-gateway statements inoperable. The workaround is to disable ip routing globally (config t, no ip routing), configure a default route instead of a default-gateway (e.g. config t, ip route 0.0.0.0 0.0.0.0 <default-gateway> ), or disable IP routing using the following cli command:

my config in my HP SW (I use trunk port 24 to c3600):

From SW i can't ping vlan 100 or other vlan's I also debug arp packets and see that the packets arrive to router but don't get out. Any help ?
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
