  • 1.  attached bit not installed on the routing tables

    Posted 08-09-2022 17:02
    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?
