ospfd: Modifying LSID generation algorithm
Description:
This LSID alogithm added as per rcf2328 Appendex-E recommendation.
This applies only for AS-external lsas and summary lsas.
As an example of the algorithm, consider its operation when the
following sequence of events occurs in a single router (Router A).
(1) Router A wants to originate an AS-external-LSA for
[10.0.0.0,255.255.255.0]:
(a) A Link State ID of 10.0.0.0 is used.
(2) Router A then wants to originate an AS-external-LSA for
[10.0.0.0,255.255.0.0]:
(a) The LSA for [10.0.0,0,255.255.255.0] is reoriginated using a
new Link State ID of 10.0.0.255.
(b) A Link State ID of 10.0.0.0 is used for
[10.0.0.0,255.255.0.0].
(3) Router A then wants to originate an AS-external-LSA for
[10.0.0.0,255.0.0.0]:
(a) The LSA for [10.0.0.0,255.255.0.0] is reoriginated using a
new Link State ID of 10.0.255.255.
(b) A Link State ID of 10.0.0.0 is used for
[10.0.0.0,255.0.0.0].
(c) The network [10.0.0.0,255.255.255.0] keeps its Link State ID
of 10.0.0.255.
