PIM over MCT intermediate router functionality
MCT peers support intermediate router functionality by accepting PIM neighbors on
specic interfaces, thus routing multicast trac as
fully functional PIM devices acting as upstream and downstream routers.
MCT peers support multicast routing (PIM) on Cluster Client Edge Port (CCEP) and Inter-Chassis Link (ICL) interfaces.
PIM states between MCT peers are synchronized by sending the control packets natively over ICL. The nature of the MCT LAG requires
this. Packets from the MCT client on the CCEP ports are received by only one of the MCT peers. Hence the control packets that are
received natively on the CCEP ports are sent over ICL to synchronize the states. The Join or Prune and Asserts are synchronized to
maintain the Outgoing Interface (OIF) state for the CCEP ports on both peers. For CCEP OIFs created by PIM joins, only one of the
MCT peers forwards the trac and the other peer drops the trac.
These are the general rules followed for the control packet handling algorithm.
• Control packets originated from MCT peers will be ooded on MCT VLAN. Exceptions are Assert packets and Join packets
triggered only for ICL OIFs.
• Control packets received on any port of MCT VLAN are ooded on MCT VLAN.
• Control packets received on ICL are ooded in a controlled manner on MCT VLAN based on remote CCEP status, that is,
based on whether they are up or down.
Control and data packets received on an ICL port are processed by searching the source MAC of the packet in the MAC table to
determine the packet ingress port as follows:
• If the source MAC is learned on CCEP port, the packet ingress port will be a CCEP port.
