Hi All, Was hoping someone can provide some advice with regards to troubleshooting a particularly painful multicast issue.
The set up isnt particularly complex: Servers <>Switch<>Tunnel router (RP) >>>>> GRE over WAN >>>> Tunnel router <>Switch<>Servers The tunnel router interfaces have been configured with the TCP mss adjust mtu command and set to 1400. Everythings been up and working for a year but recently weve been experiencing issues with mcast and can see dropped packets when using a sniffer on the server. The suspicion lies with the WAN provider who has recently made changes but extended pings/sweeps over the WAN shows no drops. Has anyone any ideas or experience on how to troubleshoot packet loss over GRE for multicast?
