Ok, last week BGP command "neighbor x.x.x.x default-originate" crashes my
router with IOS C2500-JS-L.121.BIN.
So I downgrade from 12.1 Ent Plus to 12.0 Ent Plus and all is well.
This weekend I start studying again and I find another bug (I THINK). I was
using c2600-d-mz.120-7.T.bin on my 2610. I just recently upgraded to this
version.
Telco isdn switch will "not" accept my spids. "Show isdn stat" tells me
spids were SENT but NOT VALID (ALSO LAYER 1 AND 2 ARE ACTIVE...MULTIPLE
FRAME ESTABLISHED, TEI ASSIGNED....BLAH BLAH BLAH).
I cannot get these spids validated no matter what I do.
Then I downgrade by copying IOS 11.3 from TFTP to flash and reloading. The
router comes up, I bounce the bri0/0 interface and "walla," spids VALID!!
I don't know what the deal is. Is there something "extra" I need to do with
12.0 or is this another bug?
I don't have time to deal with bugs/TAC issues. I'm trying to study here!!!
