Multicast. PIM
Goal: Configure PIM in the network.
Lab objectives:
- Configure PIM on all devices (except access switches). Any dynamic routing protocol may be used for IP connectivity.
- Document the work plan, address space, network diagram, and configurations.
An optional extension: implement Multicast together with VxLAN (may be addressed later).
The topology is based on the OSPF lab, extended with multicast support.
Since EVE-NG runs without a GPU (console only), a custom QEMU image was built for multicast source/client roles. The multicast source uses the tstools package; clients use smcroute.
