RIPng is incompatible with dual-stack technology.
All interfaces have been configured with the incorrect IPv4 addresses.
RIPv1 or RIPv2 needs to be configured in addition to RIPng to successfully use IPv4.
When IPv4 and IPv6 are configured on the same interface, all IPv4 addresses are shut down in favor of the newer technology.

It provides internetworking and WAN access interface ports that are used to connect to the service provider network.
It provides termination for the digital signal and ensures connection integrity through error correction and line monitoring.
It converts the digital signals produced by a computer into voice frequencies that can be transmitted over the analog lines of the public telephone network.

The router forwards the frame to all ports in the network and learns the address from the reply frame.
The destination host IP address is embedded in the DLCI.
The router searches Inverse ARP tables for maps of DLCIs to IP addresses.
A table of static mappings can be searched.
The router broadcasts a request for the required IP address.
Lower latency and jitter
Variable bandwidth capacity
Fewer physical router interfaces

Company B has a higher volume of POTS voice traffic than Company A.
Company B shares the conection to the DSLAM with more clients than Company A.
Company A only uses microfilters on branch locations.
Company A is closer to the service provider.

Uploads typically offer larger transfer rates than downloads.
Service providers deploy DSL in the local loop of the telephone network.
DSL download rates are reduced by large volumes of POTS voice traffic.
Filters and splitters allow POTS and DSL traffic to share the same medium.
DSL is a shared medium that allows many users to share bandwidth available from the DSLAM.
