Configuring the Routing Protocol Causes a Reset of the Cable Modems
Be aware that when configuring a routing protocol on an interface, the Cisco IOS software must reset
the interface to enable the change. This normally does not significantly affect operations on the interface,
except that when this is done on a cable interface, it causes all cable modems on that particular
downstream to reinitialize, potentially interfering with data transmission on that downstream. Therefore
you should use the interface configuration commands, such as router rip, on a cable interface only when
a minimum of subscribers would be affected.

The DOCSIS 1.0+ QoS Enhancements is a set of Cisco's Quality of Service extensions to DOCSIS 1.0 to enable basic VoIP
service over the DOCSIS link before DOCSIS 1.1 becomes available. The main enhancements include support for dynamic
creation and teardown of flows during voice calls, support for one new unsolicited grant service (UGS) slot scheduling
mechanism for voice slots, and per IP-precedence rate shaping on the downstream.
