Abstract

Methods and apparatus to convert configuration data associated with a first router are disclosed. Example methods include receiving via a graphical user interface a user selection of a first port associated with the first router and a second port associated with a second router and detecting data flow on a subinterface associated with the first port. The method also includes converting the configuration data from a first format to a second format based on the detected data flow, the configuration data being associated with the subinterface. In some examples, the method further includes preventing conversion of the configuration data associated with the subinterface if data flow is not detected.

First claim

What is claimed is:

1. A method to convert port configuration data collected from a first router, the method comprising:
in response to receiving a determination that Internet Protocol pool interfaces are to be converted, identifying, with a processor, a first Internet Protocol address and a last Internet Protocol address associated with an Internet Protocol pool configuration statement;
subtracting, with a processor, a third octet in the first Internet Protocol address from a third octet in the last Internet Protocol address;
based on subtracting the third octet in the first Internet Protocol address from the third octet in the last Internet Protocol address, identifying, with a processor, a corresponding number of subsets;
determining, with a processor, a mask number based on the corresponding number of subnets;
using the mask number to convert, with a processor, the Internet Protocol configuration statement; and
transmitting the converted Internet Protocol configuration statement as an Internet Protocol configuration file to a second router.

2. The method of claim 1 further including:
creating, with a processor, a configuration delete file, the configuration delete file identifying configuration data to be removed from the second router prior to migrating a set of routes from the first router to the second router; and
using the configuration delete file to remove existing configuration data associated with a port of the second router, the port of the second router being associated with data lines to be migrated from the first router to the second router.

3. The method of claim 1 further including:
receiving, via a graphical user interface, a user selection of a first port associated with the first router and a second port associated with second router;
detecting data flow on a subinterface associated with the first port; and
converting the port configuration data from a first format compatible with a first router to a second format compatible with the second router based on whether data flow is detected, the port configuration data being associated with the subinterface.

4. The method of claim 3 further including preventing conversion of the port configuration data, if data flow is not detected.

5. The method of claim 3 further including verifying, with a processor, that a first number of permanent virtual circuits identified in the port configuration data collected from the first router is equal to a second number of permanent virtual circuits identified in the port configuration data after conversion to the second format.

6. The method of claim 3 further comprising receiving, via the graphical user interface, an input indicating whether a distribution route configuration is to be generated.

7. The method of claim 3 further including:
determining whether the port configuration data includes an interface description;
if the interface description is not included in the port configuration data, defining an Internet Protocol interface with a unique name and Internet Protocol addressing for a corresponding permanent virtual circuit interface associated with the second router; and
if the interface description is included in the port configuration data, defining an Internet Protocol interface with a unique name and Internet Protocol addressing for a corresponding permanent virtual circuit interface associated with the second router; and
if the interface description is included in the port configuration data, using the interface description as the Internet Protocol name and Internet Protocol addressing of the corresponding permanent virtual circuit interface associated with the second router.

8. An apparatus to convert port configuration data collected from a first router, the apparatus comprising:
a memory having machine readable instructions stored thereon; and
a processor to execute the instructions to perform operations comprising:
in response to receiving a determination that Internet Protocol pool interfaces are to be converted, identifying a first Internet Protocol address and a last Internet Protocol address associated with an Internet Protocol pool configuration statement;
subtracting a third octet in the first Internet Protocol address from a third octet in the last Internet Protocol address;
based on subtracting the third octet in the first Internet Protocol address from the third octet in the last Internet Protocol address, identifying a corresponding number of subnets;
determining a mask number based on the corresponding number of subnets;
using the mask number to convert the Internet Protocol configuration statement; and
transmitting the converted Internet Protocol configuration statement as an Internet Protocol configuration file to a second router.

9. The apparatus of claim 8 , wherein the operations further include:
creating a configuration delete file, the configuration delete file identifying configuration data to be removed from the second router prior to migrating a set of routes from the first router to the second router; and
using the configuration delete file to remove existing configuration data associated with a port of the second router, the port of the second router being associated with data lines to be migrated from the first router to the second router.

10. The apparatus of claim 8 , wherein the operations further include:
receiving a user selection of a first port associated with the first router and a second port associated with the second router;
detecting data flow on a subinterface associated with the first port; and
converting the port configuration data from a first format compatible with the first router to a second format compatible with the second router based on whether data flow is detected, the port configuration data being associated with the subinterface.

11. The apparatus of claim 10 , wherein the operations further include preventing conversion of the port configuration data, if data flow is not detected.

12. The apparatus of claim 10 , wherein the Operations further include verifying that a first number of permanent virtual circuits identified in the port configuration data collected from the first router is equal to a second number of permanent virtual circuits identified in the port configuration data after conversion to the second format.

13. The apparatus of claim 10 , wherein the operations further include receiving an input indicating whether a distribution route configuration is to be generated.

14. The apparatus of claim 10 , wherein the operations further include:
determining whether the port configuration data includes an interface description;
if the interface description is not included in the port configuration data, defining an Internet Protocol interface with a unique name and Internet Protocol addressing for a corresponding permanent virtual circuit interface associated with the second router; and
if the interface description is included in the port configuration data, using the interface description as the Internet Protocol name and Internet Protocol addressing of the corresponding permanent virtual circuit interface associated with the second router.

15. The tangible machine readable storage medium comprising machine readable instructions which, when executed, cause a machine to perform operations comprising:
in response to receiving a determination that Internet Protocol pool interfaces are to be converted, identifying a first Internet Protocol address and a last Internet Protocol address associated with an Internet Protocol pool configuration statement;
subtracting a third octet in the first Internet Protoc
