What do you consider yourself? - mostly IP centric - mostly optical/transport centric - both


The major objection against IPoDWDM: the transport people want to manage their transponders

The data/network people dont want the transport people to touch their routers

Virtual Transponders address this issue

Exposes the DWDM aspects of an IPoDWDM interface

Integrate into Cisco Transport Controller using XML

Allows for segmented management of the transmission and IP networks

Capability to establish and monitor an optical path starting from DWDM interfaces located into XR based routers (CRS) by means of ONS manageability tools: CTC and CPO.

MSTP Rel. 9.602/9.603 manages XR Rel. 4.2.0 - 4.3.0

MSTP Rel. 9.602/9.603 uses GMPLS from NFV


Accessible from CTC Home Page or Edit -> Preferences menu option.

Skip CLI settings on the router either for creation or deletion

Set different credentials for router nodes (it is valid across all routers within the CTC network)


Dynamic LMP requires:

1. LMP enable (per node)

2. Control Channel (per node)

3. TE Links (per interface)

4. Data Link (per interface)

LMP-WDM must be disabled.


The LMP configuration will be applied on this DWDM controller
