IF I specically configure R1 and R2 to be as L1 only then
Are they required to be int the same area?
For example,
I have r1 connected to r2 both via Ethernet 0. Cisco routers by default are
L1/L2 routers. I then configure
r1
interface ethernet 0
ip router isis
net 49.001.0001.0001.0001.00
r2
interface ethernet 0
ip router isis
net 49.0002.0002.0002.0002.00
The adjaceny will be established since both routers at this point are L1/L2
regardless of different areas.
Now if I change the default settings from L1/L2 to L1 only by configuring
is-type Level-1
Will it still work with both routers in different area?
The last one
I don't change the whole default-type, but just change the interface only to
Level-1 by configuring
isis circuit-type level-1
All the help will be appreicated as I spent lot of time at CCO, but no
satisfactory answer.
Regards.
