Hi all,
The network topology is illustrated below:
WAN ------ Router ------ L3 Switch ------ Client
PIM-SD are configured on both L3 Switch and Router. The Client is going to join a multicast group, for example 239.42.1.1. This join message is received by L3 Switch and then converted to a PIM message to Router. After that, we can see such item in Router's mroute table. However, when Router insert such item into its mrouter table, it will not send the corresponding IGMP join message to WAN port. Without this join message, the Router cannot receive UDP multicast packets from the server in WAN.
So how can I configure my Router to send such IGMP join message?
