1. A method for propagating information in a network, the method comprising:
- automatically assigning an index number to an interface of a circuit switch, wherein said circuit switch is configured to be communicatively coupled to a router;
automatically transmitting said index number using said interface, whereinsaid automatically transmitting said index number using said interface uses a packet routing protocol, andsaid router is configured to communicate using said packet routing protocol; and
automatically transmitting said index number using at least one additional interface of said circuit switch, whereinsaid automatically transmitting said index number using said at least one additional interface uses said packet routing protocol,said interface and said one additional interface are interfaces among a plurality of interfaces of said circuit switch,said interface is configured to be coupled to a link,said circuit switch is configured to store a table, andsaid table comprisesan entry indicating said index number,an entry indicating a function of said link, andan entry indicating a predetermined number of contiguous frames that may be transmitted over said link.

Abstract
Disclosed is a method and associated apparatus for automatically propagating circuit information in a network. In one embodiment, a network includes multiple circuit switches that are coupled using communications links. Information relating to the communications links are automatically propagated in the network using a protocol used by routers in communicating with other routers.
