I'm trying to implement extended vlans on two core switches that are VTP servers, but am unsuccessful. The switches have SupIV's with 12.2(25)EWA8 code, and have VTP domain and passwords set. Also VTP mode V2 is enabled on both, as well as the "spanning-tree extend system-id" command enabled.
I find that I can add an extended vlan to either core (Example vlan 1112), but the vlan is not propagated to the other Core switch, which is also set as a VTP Server. Vlan additions from either Core switch succesfully create/distribute to the adjacent VTP server for vlans <1005, so I know the VTP Domain, VTP Password, and turnking between the switches is working.
When I do a "show spanning-tree summary | include extended" there is no data. Troubleshooting on Cisco site states I should see, "Extended system ID is enabled"
I have looked at the following Cisco site and have followed the configuration examples.
Any help would be appreciated.
