Hi Alex, > Seems it's time to put the cards on the table :) What kind of > information do you think we would put in link records? I think we can have something equivalent to what ISIS has (TLV for experimental use). http://www.ietf.org/internet-drafts/draft-ietf-isis-experimental-tlv-04. txt . We could also use it for sending messages for informational purposes.

Seems it's time to put the cards on the table :) What kind of information do you think we would put in link records? We need to keep in mind that we only have one router LSA per router and its size needs to be well-controlled. I personally would be reluctant to put there anything that isn't related to the basic topology abstraction. > I think adding the option bit as you suggest will help for sure.

If there is demand to add information which can cause routing > changes, we could go in for the heavier extension as you suggest. This is what was done for stub and NSSA areas. I would use the same method for other extensions that affect route calculations. If they don't, then the question is whether this info belongs in the router-LSA at all. Alex
