Unanswered Question

We are using a tool to monitor a Cisco router with SNMP. Basiclly the router has 3 interfaces, they are WAN, LAN and GRE tunnel interface. The GRE tunnel bases on the LAN interface. My question is if I keep looking at the WAN interface, does that valume include all the traffic going through the GRE tunnel?

Thanks. Leo

Not sure about the actual topology, but if the encapsulated packets are going out over the WAN, then, yes, the WAN counters would include the tunnel traffic as well.
