Hi all

In the book of Cisco Routing TCP/IP Voulme 1, it mentions that the OSPF
point-to-multipoint network type treats the underlying network as a
collection of point-to-point links rather than a multi-access network,
and OSPF packets are multicast to the neighbors. This situation can be
problematic for networks whose connections are dynamic, such as frame
relay SVCs or ATM SVCs.

But it has not mentioned what is the problematic situation. Does anyone
know that?

I think that it should not be problematic because InverseARP can cater
for the mapping of the DLCI to the remote IP address even the underlying
network built on SVCs. Is that right?

Thanks.

Cheers
Stephen
