hello brothers
I am working in my lab, exactly on the isis protocol
I have the below routers:
R1, R2 are Level 1
R3, R4 are L1/L2
and R5 is Level 2
i notice the routes of level 1 routers have received on the R5 routing table but can not ping them from R5,.
also, I noticed the attached bit is not installed on all routers
can you help me with this?
R1:
