Escrow is a term used in many types of businesses, but to keep things simple, weâre going to limit this discussion to what escrow means in terms of real estate. Escrow can be three things, and if we take those Wikipedia items in reverse order, they might make a little more sense.
OTV is an encapsulation protocol that wraps L2 frames in IP packets in order to transport them between L2 domains. Typically this would be between remote datacenters, but it could also be within a datacenter if you needed an easy (expensive) way to extend a VLAN.
Introduction. OTV is a MAC-in-IP method that extends Layer 2 connectivity across a transport network infrastructure. OTV uses MAC address-based routing and IP-encapsulated forwarding across a transport network to provide support for applications that require Layer 2 adjacency, such as clusters and virtualization.o effect on existing network design. 1  Transport agnostic: OTV is IP encapsulated and can therefore use any core capable of forwarding IP traffic. 2  OTV therefore does not pose any requirements on the core transport.
