Methods, apparatus and articles of manufacture to manage routing in networks
View Patent ↗Example methods, apparatus and articles to manage routing in networks are disclosed. A disclosed example method includes identifying a first network element associated with a problematic network element; identifying a first maximum transmission unit of the first network element and a second maximum transmission unit of the problematic network element; determining whether the first and second maximum transmission units are different; and when the first and second maximum transmission units are different, identifying a value of a greater one of the first and second maximum transmission units and configuring the first network element and the problematic network element to each have the identified value.
1. A method comprising:
identifying a first network element associated with a problematic network element;
identifying a first maximum transmission unit of the first network element and a second maximum transmission unit of the problematic network element;
determining whether the first and second maximum transmission units are different; and
when the first and second maximum transmission units are different:
identifying a value of a greater one of the first and second maximum transmission units; and
configuring the first network element and the problematic network element to each have the identified value;
detecting whether a mismatch exists between a first Bellman-Ford constant associated with the first network element and a second Bellman-Ford constant associated with the problematic network element; and
when the mismatch exists, configuring the first and second Bellman-Ford constants to match.
2. A method as defined in claim 1 , wherein identifying the first network element comprises identifying neighboring network elements of the problematic network element.
3. A method as defined in claim 1 , wherein the neighboring network elements of the problematic network element are directly connected to the problematic network element.
4. A method as defined in claim 1 , further comprising determining whether an undesired condition exists in connection with a hold time and a hello interval of at least one of the first network element or the problematic network element.
5. A method as defined in claim 4 , further comprising, when the undesired condition exists, increasing the hold time to be a multiple of the hello interval.
6. A non-transitory machine-readable storage medium comprising instructions that, when executed, cause a machine to perform operations comprising:
identifying a first network element associated with a problematic network element;
identifying a first maximum transmission unit of the first network element and a second maximum transmission unit of the problematic network element;
determining whether the first and second maximum transmission units are different; and
when the first and second maximum transmission units are different:
identifying a value of a greater one of the first and second maximum transmission units; and
configuring the first network element and the problematic network element to each have the identified value;
detecting whether a mismatch exists between a first Bellman-Ford constant associated with the first network element and a second Bellman-Ford constant associated with the problematic network element; and
when the mismatch exists, configuring the first and second Bellman-Ford constants to match.
7. A storage medium as defined in claim 6 , wherein identifying the first network element comprises identifying neighboring network elements of the problematic network element.
8. A storage medium as defined in claim 6 , wherein the neighboring network elements of the problematic network element are directly connected to the problematic network element.
9. A storage medium as defined in claim 6 , wherein the operations further comprise determining whether an undesired condition exists in connection with a hold time and a hello interval of at least one of the first network element or the problematic network element.
10. A storage medium as defined in claim 9 , wherein the operations further comprise, when the undesired condition exists, increasing the hold time to be a multiple of the hello interval.
11. An apparatus comprising:
a memory comprising machine readable instructions; and
a processor to execute the instructions to perform operations comprising:
identifying a first network element associated with a problematic network element;
identifying a first maximum transmission unit of the first network element and a second maximum transmission unit of the problematic network element;
determining whether the first and second maximum transmission units are different; and
when the first and second maximum transmission units are different:
identifying a value of a greater one of the first and second maximum transmission units; and
configuring the first network element and the problematic network element to each have the identified value;
detecting whether a mismatch exists between a first Bellman-Ford constant associated with the first network element and a second Bellman-Ford constant associated with the problematic network element; and
when the mismatch exists, configuring the first and second Bellman-Ford constants to match.
12. An apparatus as defined in claim 11 , wherein identifying the first network element comprises identifying neighboring network elements of the problematic network element.
13. An apparatus as defined in claim 11 , wherein the neighboring network elements of the problematic network element are directly connected to the problematic network element.
14. An apparatus medium as defined in claim 11 , wherein the operations further comprise:
determining whether an undesired condition exists in connection with a hold time and a hello interval of at least one of the first network element or the problematic network element; and
when the undesired condition exists, increasing the hold time to be a multiple of the hello interval.
