Hey guys,
Got another network puzzle.
R4 is the hub of a spoke and hub FR cloud connecting R5 and R3.
All config's are on multipoint interfaces.
There's also an isdn circuit between R4 and R5.
This task forbids me to use any dynamic mappings or dlci's that weren't
specified.
I'm to config FR end2end keepalives (FREEK) in order to detect if R5's F/R
connection to R4 is actually down.
R5 is to poll R4 and R4 is supposed to respond.
I configured everything as stated and it seemed to work - at least for a
while. But, periodically, I would lose connectivity.
Since FREEK has to be configured in a map-class, I wanted to assign the
map-class to the particular dlci's relevant to this task.
But, as it turns out, unless I'm mistaken, there's no class option available
in the fram map ip statement. So, instead, I just assigned the map-class to
the interface or multipoint subinterface.
BTW, the idea was that if the f/r link between R4 and R5 went down, this would
trigger R5 to call R4 over the isdn circuit.
After struggling with this for a while, I simply had to turn off FREEK cause
it was messing up ospf and the other IGP's running in the network.
Anyone know how I should have solved this problem? Or, more specifically, how
should FREEK be configured on a multipoint interface? I've only seen it
configured on p2p interfaces.
All ideas are greatly welcomed.
Thanks, Tim
