Hi,
Can someone shed some light on the following limitation of EoMPLS?
Layer 2 connection restrictions:
- You cannot have a direct Layer 2 connection between provider-edge
routers with EoMPLS
Why is this?
I have a MAN running MPLS where my PE are directly connected. I need
to do extend my datacenter LANs from location A to location B. I was
thinking of using EoMPLS but this limitation is bothering me because
I don't understand this limitation.
Anyone care to explain?
Can't see a problem with this and have implemented basically exactly
what you have outlined. We are running 2 pairs of 6500s providing
redundant 10GigE paths between a couple of datacentres. They act as
PEs and provide port based EoMPLS xconnects to other 6500s at the
DC's. Those 6500s run dot1q over an etherchannel constructed from a
bundle of these EoMPLS vc's. Works very well. Only issue is layer 2
fault identification (see recent thread on Fast UDLD Timers for the
ugly details).
