[Csci551-talk] LSA packet structure

[Devarshi Shah]

The difference is this :

Responsible routes = routes that you are responsible for handling. For
example, if router 1 aggregates 192.168.0.0/16, it is said to be
"responsible" for 192.168.0.0/16. The project definition says that a router
may choose to propagate the injected (external) routes as its own - this
means that for example, if 12.0.0.0/8 is injected into router 1, it can now
propagate 12.0.0.0/8 as one of the routes it is "responsible" for. Thus, the
"responsible" routes IS NOT the current link state of the router.

On the other hand, links = number of directly connected neighbours. It does
not bear any relation to the responsible routes. This can represent the
current link state of the router.

Hope that helps !

Hi,

I still dont get the difference between responsible routes and links. The 
responsible routes would include the current link state of the router and
that 
number would be equal to the number of links right ? So why are there two 
separate fields ? Why not have the far-end router id field as part of the 
responsible route fields ?

Am i getting something wrong here ??

thanks,
Rohit
