All,
I'm currently comparing these two technologies in an effort to offer a
Layer 2 VPN service on our backbone. Our network is currently not MPLS
enabled. Below is what I perceive as the pros and cons of each
technology. If anyone has thoughts on or experience with either one of
these protocols I'd like to hear your opinion.=20
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 services like
L3 VPNs and TE
Con
---
Enabling MPLS is a huge change
Changing the forwarding paradigm in the network exposes us to new and
interesting bugs and stability issues
L2TPv3 VPN
Pro
---
Doesn't require MPLS/Much smaller change =20
Con
----
Although standard, only supported by Cisco currently (I think)
Requires special tunneling card in GSR routers. =20
