Mike, I am not sure if this helps or not, or the # of VPN's, But have you considered Cisco's GRE tunneling? This will allow multi-protocol also.. Do a Search for DMVPN on the Cisco site.. This is a brand new feature... Later, Jim

Your point is very well received. One of the design requirements for our VPN solution will be the ability to allow customers to use non-IP protocols. I don't think RFC2547bis will work for this. However if we do go the MPLS route then RFC2547bis will be available as a product as well as Layer 2 VPNs. That's definitely a benefit. -----Original Message----- From: David Bigge [mailto:david.bigge () giftofsite com] Sent: Friday, April 04, 2003 10:56 AM To: Mike Bernico; nanog () merit edu Subject: Re: Seeking Advice: L2TPv3 vs. Martini Draft MPLS Mike, An unsupported standard might as well not be a standard. I would lean towards the most openly supported standard- MPLS. Along with not letting one vendor bend you over the barrel, this openess also flushes out any problems for a more stable long-term network. You don't talk about 2547bis VPNs. Are you considering that also? We use a competitor of Cisco's equipment so I am biased. My 2 cent.

Our network is currently notMPLSenabled. Below is what I perceive as the pros and cons of each technology. If anyone has thoughts on or experience with either oneofthese protocols I'd like to hear your opinion. Thanks Mike Martini VPN Pro ---- Supports MPLS TE for each VPN, making it more PVCish Enabling MPLS would open up the "MPLS tool box" for other serviceslikeL3 VPNs and TE Con --- Enabling MPLS is a huge change Changing the forwarding paradigm in the network exposes usto new andinteresting bugs and stability issues L2TPv3 VPN Pro --- Doesn't require MPLS/Much smaller change Con ---- Although standard, only supported by Cisco currently (I think) Requires special tunneling card in GSR routers.
