MPLS is a one of a technology to route packets fastly in
the internetwork, were as OSPF is a Routing protocol.
MPLS technology is nothing but adding a lable contains
virctual path to reach the destination network(VRF) to the
data packets. once the labled packets are received by the
router,the packet is switched directly to next router
through the virctual path based on the VRF details, This
means there is no need for routing table look up, and
because of this the switching is very faster than other
technology.

Answer / santosh
OSPF is a Layer 3 routing protocol. When traffic is to move
using routing protocol OSPF, the router has to do a layer 3
lookup. Whereas in case of MPLS, the traffic is to move,
the router just have to lookup the Label. So the traffic
switching takes place faster with MPLS.
Point to remember is that MPLS cannot be implemented unless
the network is implemented with some IGP like OSPF.

Answer / ziauddin khan
As far as i know that Link-state routing protocols such as
OSPF flood routing information among a set of routers that
are not necessarily adjacent, whereas label-binding
information is distributed only among adjacent routers.
This makes link-state routing protocols unsuitable for
distributing label-binding information.

Which two statements about the store and forward switching method are true? (Choose two) A. Latency remains constant regardless of frame size. B. Latency through the switch varies with frame length.
