Assume I have the lab setup as the following:

R1 -(eigrp)- R2 -(ospf)- R3

loopback0 on R2 is advertised by eigrp. R2 and R3 are connected with Frame
Relay and ISDN.

Is it must to configure "passive-interface loopback0" on R2 in order not to
sent multicast traffic over ISDN link?

router eigrp 90
  passive-interface loopback0

Thanks,

PD
