I had the same problem in "real life". Telco upgraded frame switch. OSPF
would stick/die at ex-start. Also IPX EIGRP could not form neighbor
relationships. Telco keep saying frame switch wasn't problem, problem was
too much IPX traffic and too many IPX SAPs (we do have 4000 SAPs). After
three the finally looked at Frame switch and "Baaaammm!!" came clear while
testing.

Hi All,
Rebooted the frame switch this morning and all is well? Looked at every
other conceivable problem except the most basic one! I had used the same
config for other labs so I had 'ass-umed' that it would be fine
Thanks to everyone for their input! :- )
