We have a situation where some equipment did not come in and we are trying to bring up a circuit that was going to be GigE over SONET end to end but isn't possible at this time. What we are going to try is to have a 7200 router with a GigE interface and a OC3 POS interface. On the other ende is a SONET Optical switch (Lucent LambdaUnite) with a OC3 and a GigE interface. The Lucent is bridging the ethernet traffic into a VT for of the OC3. This is standard operations there. On the router I was going to set up a bridge group between the GigE and the POS interface, hoping this will accomplish the same thing. Now will the framing of these devices make this totally incompatiable or is there a chance to make the C2 bytes match up or anything. I am guessing the the ethernet traffic will be messed up going into a POS interface when it tries to come out the other end. Thanks for the help.
