Hi all, can the FSIP serial or SSIP serial on 7507 support ip multicast well? I have config the multicast on 75's SSIP 2M serial, but the effect is bad, lost packets,and if I change the line and same config to the 4T serial on 3661, the multicast effect is very good. The config on 75 and 36 is the same, and the mem on 75 is 128M, IOS is 12.1.
Pls help, thanks
