First, the no ip forward-protocol udp 67 command is configured on R2. This needs to be removed in order to allow DHCP Broadcasts to be sent.

Second, the DHCP pool has no IP addresses to assign. The ip dhcp excluded-address 10.2.2.1 10.2.2.255 command should be removed from R3.

The issue is that R1 is re-advertising the static default route it receives via EIGRP to R2. This route is more preferred from the default route advertised by R4 and therefore needs to be filtered appropriately using a distribute list as follows:

The EIGRP stub router needs to be configured to advertise and redistribute static routes. The following configuration should be implemented on the router:

First, IP Multicast routing is disabled on R3. This needs to be enabled via the ip multicast-routing global configuration command. Dense Mode forwarding is already enabled for Serial1/2 and 1/3 so no additional changes are required on this router.Second, while IP Multicast routing is enabled on R4, Sparse Mode Forwarding is enabled on Serial0/0 and 0/1. This should be changed to Dense Mode forwarding using the ip pim dense-mode interface configuration command. No additional changes are required on R4.
