Hi, I have a query related to the RPF check from RFC 6325. Let us say a TRILL domain setup has about 6 RBridges each with a single nickname and 6 multicast trees are computed by each RBridge in the TRILL domain and the trill domain setup is as shown below. RB1-------RB2--------RB3 | | | | | | RB4------RB5----------RB6 As per my understanding each RB will have RPF entries that are equal to the ingress interfaces on that RB. For e.g RB1 has two interfaces hence it has two RPF entries and RB2,RB5 will have 3 RPF entries since it has 3 interfaces or to state the number of RPF entries on each RBridges depends on the number of ports that are part of the multicast trees on that particular RBridge. Please correct me if my understanding is not correct. Regards Ram
