Is there a way to configure payload compression FRF9 just between Hub and one of the spokes, considering Hub is configured with multipoint interface?
Tests indicates that it does not work.
R2 is the hub. R5 and R7 are spokes.
If not configuring "payload-compression FRF9 stac software" on the map to R5 (frame-relay map ip 172.16.200.5 702), ping to R5 does not work.
It seems R7 does not sent uncompressed packets to R5:
r7(config-if)#do sh run int ser 1/2
