Hi Mike,

Thanks for the response ... I found the problem, not quite sure what
happened though - the routing table entries on the AIX box for site B
had disappeared ... reason why that is odd is the only person who
would have any clue how to remove them is me, and obviously I did not
do it lol ... only other explanation I can think of is some sort of
table corruption but I would have expected the lot to go if that
happened, dunno whether its possible for a single route to corrupt ?

Anyway all is working fine now, many thanks for the pointer.

Cheers,
Jeff.
