in thread Strange results from unpack when trying to decode OSPF LSA's from the OSPF MIB

Hi,

Thanks for the reply. I also noticed that but I find it hard to believe that 6 different routers running different operating systems and from two different vendors would give me the same data, i.e. the 32.

Ethereal has the same hex data for the ospfLsdbAdvertisement from the devices as my dump.

I've also checked the LSDB's in the routers themselves and they're reporting the correct data, as expected.

Any other ideas? Do you think the decode looks okay?

thanks, Matt

    I have no idea what OSPF, LSDB or LSA means. All I know is that your data is consistent with your dump.

      Hi,

      Thanks for the reply, it's good to hear some feedback re: valid decoding. I love your scratchpad btw, great stuff.

      Here's a five second OSPF headsup if you're interested:

    • OSPF - Open Shortest Path First, routing protocol that uses the dijkstra algorithm.
    • LSA - Link State Advertisement, topology-related data sent between routers running OSPF.
    • LSDB - The Link-State Database, held by routers running OSPF and describes a topology.

      Thanks once again, Matt.
