Issue#1:
The firstissue I wentthroughwasthe zone basedfirewallswere notconfigured properly. Iwent

Issue # 2:
While Configuringthe Multicastingbetweenthe routers(RDandRC) I saw that the ip multicast-routing
commandon RD was notconfiguredbefore definingthe modes(Sparse orDense andthe interface.
secondlythe IPaddressof RC of ip pimrp-addresswaswrongwhichiscoloredinRED below.

Thirdissue wasof VTP. VTPpruningwas disabledwhenIcheckedthroughthe show VTPStatus
