Can anyone point me in the direction or explain how IOS version numbers work? A while back, this vulnerability came out - http://www.cisco.com/warp/public/707/cisco-sa-20070124-crafted-tcp.shtml
12.0T is listed as vulnerable, as is 12.1T. Output from show ver on a router here shows:

I've got a 2620 that I am trying to setup MLPPP across 2 T1s on. Spent over an hour on the phone with the ISP trying to get this working. When I mentioned it was a 2620, he immediately said that it was probably too old of a version of IOS.

cisco 2620 (MPC860) processor (revision 0x600) with 26624K/6144K bytes of memory.
I was able to bring either T1 up as PPP, but they would not pass any traffic. I was also able to bring both T1s up as PPP, add them to a multilink group, and have that multilink show up/up, but not pass traffic.
I'm running a very basic config on this. Any ideas on what I need to do to get this running correctly?

I was able to ping and telnet by IP address only when the MLPPP config was in place, or when I was only using a single T1 as PPP. As soon as I'd have the ISP update their end to not be MLPPP, and change back to HDLC, and I switched back to HDLC on my end, all normal traffic would work.

interface Serial0/1 (when I had the ISP switch to PPP, both interfaces looked exactly like this)
