Many thanks to jjn_at_sanger.ac.uk who gave us the following info
The Fore documentation about anycast addresses relate to UNI version
4. This isn't supported on DU. When 'making up' anycast addresses just
change the first byte for 0x47, like a 'normal' nsap address...

The anycast address is set up on the DLE services. It would have been
assigned when the LANE services were set up.
There is no special configuration required on the NIC card.
When the LANE services are set up on the switch (conf lane les) you'd
specify the anycast address.
So basically we need to make a config change to the anycast address on the FORE
switches. Obviously this is not something we can just do without some detailed
testing (i.e will our other servers with FORE cards still work with a updated
anycast address ?). I'll post more info in the new year.

We have recently started using Digital ATM cards. We are trying to configure a
ATMworks351 (part no 3xDGLPA-UA). The card is patched into a FORE switch. The
following config file exists which is run from a 'atmconfig source' command
run /sbin/atmconfig up driver=lpa0
run /sbin/atmconfig wait state=up driver=lpa0
run /usr/sbin/atmsig up driver=lpa0 wait
run /usr/sbin/atmelan create driver=lpa0 name=backup
run /usr/sbin/ifconfig elan0 10.0.225.12 netmask 255.255.240.0 up
The name of the elan we want is 'backup' we do not use classical IP.
I think the card set up is failing at the address registration phase and
therefore we are getting no IP action. The following commands give
-------------------------------------------------
COMMAND atmsig status driver=lpa0 GIVES
UNI version on lpa0: 3.0
Q.SAAL state on lpa0 (vpi = 0 vci = 5) :
State of SSCF as perceived by Q.93B : Connection established state.

SSCOP state : Ready for data transfer.
Q.93B State on lpa0 (vpi = 0 vci = 5) : Ready for data transfer.

ILMI State : Address registered.
