VTP across routers

Hi. I'm new to Cisco and just wondering how VTP would work across multiple router.



I've been using one 2950 switch and 2621 router to play with VLAN and inter VLAN router I've been using one 2621 FA0/0 and did make a subinterfaces for each VLANs and designated one switchport to funtion as trunk.



All I did configured correctly. but just curious as how would VTP would work across multiple router? would I need to use high end ley 3 switch to make that work? or 2621 would suffice. If so, how would I go about configuring it so that fast ethernet port would carry VLAN traffic.



I hope somebody could help me please.



thanks in advance.

VTP is a layer 2 protocol

To trasnport it across routers would require use of something like L2TP

see Cisco doc "Transparent Layer 2 Protocol Tunneling and PDU Filtering"

Exactly - VTP would have to be tunneled across a layer-4 boundary somehow.

Why would you want VTP to cross a router anyway? I can't see that makes any sense at all really, unless you want to c> VTP is a layer 2 protocol
