Hi,
My issue is i have created two vlans in 4948 core switch one for servers and other for systems(users) . We have created access ports for server vlan in core switch itself and connected the servers in those ports and trunks have configured between coreswitches and access switches to be connected to users,and we have enabled intervlan routing .Now there are some users having software clients which need multicast updates from a particular server. But since all the servers and systems are in seperate vlans multicast packets are not coming to clients . can any one send me a configuration and explain the same how to implement that for this kind of scenario.

hello Santosh,
on core 4948
conf t
ip multicast-routing
int vlan 10
desc servers
ip pim sparse-dense-mode
int vlan 20
desc clients
ip pim sparse-dense-mode
int loop1
ip address 10.1.1.1 255.255.255.255
ip pim sparse-mode
! previous ip should be advertised in routing protocols
ip pim rp address 10.1.1.1
Hope to help
Giuseppe

here does that 10.1.1.1 refer to the multicast ip address(example) ?
because the server vlan is in 172.16.0.254 and users/system vlan is in 172.16.100.254 both /24 .

With PIM sparse mode you need an RP (Rendevous Point). The recommendation is to use a loopback address. The loopback address can be any IP you want, Giuseppe just chose 10.1.1.1 as an example. The RP address does not need to be from either the server or client vlan.
