Re: mpls pe-ce

Just from a point of view, if I was a Service Provider offering this service
and if I knew my customer doesnt know well how to manage his network and if
the design was really simple, yes, why not to go with RIPv2 ? At the end,
yes, it pretty much depends on the design and you can go with anything, for
really complex networks with potential growth in the future, OSPF scales
well, so, many aspects we have to take in consideration before choosing what
protocol to stick with, but as stated, they are all VRF aware and they all
do the same job, but in a different way, with 3 single commands you can get
RIPv2 running on the CE side and it is really simple for a customer with not
much knowledge.
