Hi all, I'm wondering if there is anyone willing to share any experiences they have had with Cisco 7200 series equipment (specifically relating to the G2 NPE) and any 12.4 based IOS. We were initially advised by Cisco to run 12.4(4)-XD7, however upon introducing our first G2 into the network, the vpdn target routers had a ~20% CPU usage increase, while the G2 itself showed signs of incorrectly establishing tunnels. Changing back to a G1 NPE (same config) and everything works as expected. Cisco has recommended that we move to a 12.2 SB IOS for the G2, however I'm wondering what other people are doing. On another note, it seems as though it is not possible to recover a G2 from a rommon state with invalid bootloader images or corrupt bootflash:. There are no commands in the rommon to allow Xmodem uploads via the console, nor any networking functions. I also noticed that it seems to be impossible to load the bootloader from a CF card - even though you can list the contents of the CF card. Does anyone have any recovery techniques that I'm not aware about in a real world failure scenario? -- Steven Haigh Email: netwiz@crc.id.au Web: http://www.crc.id.au Phone: (03) 9017 0597 - 0404 087 474

It didn't seem quite right to us either.

We are running 12.2(31)SB5 and we have been very pleased. We are using MPLS, BGP, ISIS, CEF, SNMP, and TACACS+ with I/O-2FE, 3 GE fiber SFPs, PA-MC-T3s, and PA-FEs.

That sounds disturbing. I can't imagine they would not have a way to recover using TFTP or flash. -Robert Tellurian Networks - Global Hosting Solutions Since 1995 http://www.tellurian.com | 888-TELLURIAN | 973-300-9211 "Well done is better than well said." - Benjamin Franklin
