Hi group,

I have some questions regarding ISIS and designated IS (DIS).

1) I know that I can change the isis priority per interface. Is the DIS eleceted per LAN segment or per area?
2) Is a DIS elected/required also for FR point-to-multipoint connections? Which implications does this have to hub-and-spoke type configurations?
3) What's the easiest way to figure out which router is elected as DIS?

Any input or link is appreciated.

-Stefan
