Hi Tim,
I will try this:
===============
2. In the lab, do people think it's a good idea to disable route-caching
unless explicitly forbidden? Why yes or no?
===============
I don't think it is a good idea to disable route-caching. Just if there is a task that requires it, as load-balancing per-packet.
If doing this will take out our points, that is a mistery. Maybe a direct question to Cisco CCIE group could help.
============
3. I always add the command, ip cef, to every router just so I don't have
to remember what features require this enabled. What do people think of
this?
=============
My opinion is that it is a good idea to use ip cef. I can't belive Proctors will take any point out because of this.
================
4. If I'm having reachability problems in the lab and I'm highly confident
my config's are correct, I typically resort to rebooting the routers to see
if that fixes the problem and often it does. Of course, I'm reluctant to
reboot the rtr's because it takes so long. Given the above experience, does
the GS community think it wise to first disable route-cache and/or cef
before resorting to rebooting rtr's?
===============
Rebooting the routers should be the last option.
Are you studying using 12.2T? Do not loose your time learning bugs on other IOS. There is enough bugs on 12.2T, and it would be good to be familiar with its behavior.
Today I was studying advertise-map. When I changed the access-list called by the route-map, it only worked after using 'clear ip bgp *'. 'clear ip bgp * soft' does not work.
That is the kind of thing that take time. And we want to avoid it as much as possible.
Good Luck.
Don't let the IOS get you crazy :)
It tries to do so.
