And this is what Section 8.3.1 says:
ILMI Connectivity Procedures are used to detect the establishment and
subsequent loss of ILMI Connectivity.
Establishment or loss of ILMI Connectivity does not have any effect on PVCs,
UNI or PNNI Signalling, or on the
UNI or PNNI Signalling AAL [UNI4.0, PNNI1.0], except as specified in section
8.3.3. ILMI Connectivity
Procedures are used with both physical links and virtual links (i.e. Virtual
Path Connections used by PNNI). ILMI
Connectivity Procedures are required for an ATM node, and are optional for
an ATM user.

This is beyond my current level of knowledge (and I am not sure I want to
know) but I understand that a router won't use the keepalive !?!?
