Description (partial)

Symptom:
Service Discovery uses link-local multicasts to announce and query for services that exist on the local network. By its very nature, link-local multicast advertisements will not be forwarded beyond the local segment (VLAN, Switched Virtual Interface or routed port). We will learn about services within our own local segment but when a device is connected to a different segment we won't be able to discover it.

Conditions:
A new component in IOS which allows us to extend Service Discovery beyond the link-local scope by implementing a proxy and redistribution component in IOS called Service Discovery Gateway. In its simplest form it will be enabled globally and it will listen for and learn services on all L3 interfaces of the router
