GRE tunnel

Hi,

I have the following GRE config on Cisco routers today. All multicast traffic goes via the GRE tunnel but all other traffic go via the normal path.

On Cisco router number 1:
interface Tunnel13
description multicast-tunnel, test
ip address x.x.x.73 255.255.255.252
ip pim sparse-mode
tunnel source x.x.x.48
tunnel destination x.x.x.16

on Cisco router number 2:
interface Tunnel0
description multicast-tunnel, test
ip address x.x.x.74 255.255.255.252
ip pim sparse-mode
tunnel source x.x.x.16
tunnel destination x.x.x.48

I want to replace the Cisco router number 2 with 750rb (5.0rc1).
What should be the equivalent GRE tunnel configuration on 750rb?
