Hi,
Below is my config.
(lo10)r3(s0)-------r6(s0.2)-----------(s0)r5
r6 is the hub and r3 and r5 is the spoke in the frame-relay
network.And isis is enable in r3, r6 and r5.
In the begining, r5 can see r3 lo10, however after few mins r3 lo10 will
disappear in r5. Can anyone tell me why? And why it is L2 not L1?
