Hi Bob,Yes. I added a dummy vlan on VTP server. Came out of config mode completely, saved, went back in, removed it, came out again, saved. Made no difference. Only a reload seemed to fix. Will unicast you in a moment.... G. From: [email protected] Date: Fri, 26 Oct 2012 10:37:22 -0400 Subject: Re: [OSL | CCIE_RS] VTP weirdness To: [email protected] CC: [email protected]
Hi George, Did you actually modify the VLAN database after hitting that? Remember that the VLANs won't propagate unless there's a change (or on the summary advertisement interval has passed). I've seen this same thing when setting the password on all switches and not following it up by making a change to trigger a summary advertisement. I assumed it was because something hashed differently upon the password application and didn't match back up until an advertisement had been propagated but I'd love to know more about it.

Vlans were not propagated from SW1. I bounced trunks, I converted to transparent mode and back to client or server as appropriate.I changed domains to a dummy value then back again. Nothing made any difference. Eventually, I reload all four switches, and that fixed it. My question is: what exactly causes this MD5 error, other than the passwords being different? Is there anything I missed?
