Typically there is few seconds latency when a receiver leaves a
multicast group, because of the way IGMP works.

Please see rtrmgr/config/multicast4.boot for a sample configuration
file for multicast routing. Also, see the XORP User Manual for
detail description of the configuration statements.

> How many minimum number of multicast groups it can support ?

I presume you mean "maximum" instead of "minimum".
I believe for Linux the default max. value is 20 groups (per
interface?).
See the MLD/IGMP and PIM-SM sections in the xorp/ERRATA file for
hints if you need to increase that number.

> Do we have any control like on the specific interface we can allow only the specific multicast range addresses ? 

Currently the only control is by specifying the group prefix per
static-rp or for the bootstrap mechanism.
Please add a feature request to Bugzilla for per-interface address
range control.
