I have vtp server 6500 and vtp clients N5K all its working fine, except this message (lowest numbered VLAN interface found).. I dont really know if I have to take care on this message I mean its an error message that I have to debug or its a normal message ?
If you have multiple IP addresses on your VTP server, the Local updater will use the first IP address found on your switch/router. If you utilize
sh ip int brief you will see the first interface VLAN 7 has the IP address 18.104.22.168.
If you remove the interface or IP address the local updater will use the next interface in line.
