If it is not full mesh then for this to work you need level-1 only and the
hub to be the DIS. With level-2 it will not work if I remember well,

Hi guys,
When configuring the above in a hub and spoke topology and using only the
physical interfaces, does it matter if the hub becomes the DIS? In all the
examples I've seen so far, I've never seen the isis priority command used to
force the hub to become the DIS and I don't understand why that is.
Also, are the following config's on the hub router equally valid?
Method 1 - Static mapping
Hub rtr
int s0
ip addr x.x.x.1/24
encap fram
ip router isis
fram map clns 122 broad
fram map clns 123 broad
fram map ip x.x.x.2 122 broad
fram map ip x.x.x.3 123 broad
*********************
Method 2 - Dynamic Mapping
Hub rtr
int s0
ip addr x.x.x.1/24
encap fram
ip router isis
fram interface-dlci 122
fram interface-dlci 123
It would be great if someone could explain why or why not these config's
aren't both valid.
Thanks in advance. Any feedback would be greatly appreciated, Tim
