Cisco vtp not updating dating an uneducated man

It has the ip helper defined and is working from other switches that are trunked with a different native vlan than Vlan A. Well IRS helped me determine that it's actually a VTP problem.The 3550 doesn't seem to be getting updates from the 6513. XFeature Mode Revision-------------- -------------- -----------VLAN Server 32Pruning : disabled VLANs prune eligible: 2-1000 The first thing I notice is that you are running two different versions, but I'm not certain that's the issue.

I'm on VTP exercises now and have the same lab setup as the INE lab setup exactly.i notice the MD5 digest on switch 4 is not matching all others, but this doesnt affect anything when switch 1 is not trasparent so im not sure this is a problem? Despite what you will find in Cisco documentation, a transparent 3550 or 3560 will NOT forward VTP advertisements to a switch that is not in the same VTP domain, regardless of which VTP version either switch is running.The invention of VLANs was very much welcomed by all engineers and administrators, allowing them to extend, redesign and segment their existing network with minimal costs, while at the same time making it more secure, faster and reliable!Trunks are working as per the lab config i.e switch one has 3 trunks to each of the other switches but the other switches do not have trunking directly to any other switch but switch 1.Switch 4 is not updating correctly when vlan is updated on Switch 2. When swtich 1 is client, updates are correctly made to all switches including switch 4.
