I have a simple topology of 2 Cisco 3600 routers simulated in gns3 connected via a serial link with hdlc encapsulation and using only triggered updates (no periodic ones) and I can not capture understandable Ripv2 packets. I only can capture packet with information "unknown command 9", "unknown command 10" and "unknown command 11" witch I think stands for "Update Request", "Update Response" and "Update Acknowledge" of the RIPv2 specification but no further details in each packet. I want to know if there is a problem with Wireshark handling Cisco triggered updates or the Cisco implementation of Ripv2 is done different from the specifications on the RFCs.
