Hi folks,
I am not expecting the spoke can spoke loopback.
In my case, on R2, I am not expecting to see R1's loopback and vice versa.
I just want R1(hub) see loopbacks of both spokes (R2 and R3). However, I can
not make it. Before R3 is up, R1(hub) can see R2's loopback(spoke) and vice
versa. But when I have another spoke turned up(R3), R1 can not see R2's
loopback and vice versa.
My questionis: why on the hub(R1), I can see only one spoke. Is hub(R1)
supposed to see two spokes at the same time?
Hans
