I am new to vpls and trying to get some design advice. We have vpls from the carrier and I am thinking of implement it with ospf as bgp need static peers.
The offices are in US,Europe and Asia.
I was thinking of two options:
a) Setup OSPF local within the continents and do bgp to tie the continents redistributing the summarized routes via bgp.
b) Do ospf only even between the continents no bgp.
If anyone has design it or experience with vpls, please give me you your feedback.
I will apprecaite it very much.
how many sites are involved?
if they are many you need to think of a two levels hierarchy if they are in the order of several tens an OSPF only approach can be enough.
see for example this design guide
Hope to help
