Hi How does mtu calculation work with L2 VPNs? Sample topology is:
Where and how would you implement MTU calculcation? What will decide how much MTU should be? I have different LSPs running in the MPLS network. Does LSPs have their own MTU and if yes then where do they get this MTU value from?
If I have created a logical L2 interface on top of physical interface, where will i set the mtu? On physical or logical?
Does the mtu calculation also differ based on type of port I have like Sonet/Ethernet/DS3?
Please share your knowledge on this.
