Hello everyone. I'm in need of help in a sample lab to run MLDP for MVPN. The topology is a simple CE (R1) <--> PE (R2) <--> P (R3) <--> PE (R4) <--> CE (R5). MPLS forwarding is working across the core. R1 is sending ICMP to 224.2.2.2 sourced from its loopback. I'm using 15.2 in GNS3. Below is the config and show output info. Please tell me what i'm missing in this lab.
Your comments are greatly appreciated. Thanks in advance.
Mike G.
