Any other considerations for migrating from a Frame network
up to a MPLS network ?
Also - I didn't see a MPLS newsgroup, but there was an old Frame group.
The MPLS tags dont normally get to your routers - they are within the
carrier cloud, and are there to let the telco use a common backbone for lots
of different customers.
A lot of MPLS services support more modern types of QoS etc - but there is
no real reason you need up to the minute code versions. MPLS has been around
for several years now, so obviously worked with IOS releases current when it
1st came out.
> But why does it seem that MPLS and VPN are mentioned together,
I dont know what Sprint do specifically, but it is common practice for some
carriers to use Frame Relay encap between PE and CE router - ie on the link
from customer site to the carrier cloud.
So - in theory Sprint could swap you from F/R to MPLS, and all you need is
some changes to the config on the routers.
We use it at work because you can use multiple PVCs to carry different VRFs
to give multiple logical VPNs on 1 access link.
> and yet we didn't need a VPN when using our Frame network.
A specific customer F/Relay set of PVCs and ports sort of make up a layer 2
cloud. They didnt call it a VPN as that wasnt the "in vogue" term at the
time :).

One advantage of MPLS is alternate access link support - Ethernet at
10/100/1000 Mbps for example.
QoS is pretty much standard (although usually with some extra costs), and
other things such as multicast, IP voice breakout in the cloud, Internet
feeds and hosting integration all come up frequently.
Multiple VPNs can be useful e.g. to segregate a live and test network, or
internal net and an extranet, but without needing separate access lines.
I suggest you start writing down requirements without worrying about MPLS
capabilities and then check how closely the carrier services map to that.
