The remote router updates the Frame Relay map table with DLCI 35 to reach the 10.1.10.0 network.
Inverse ARP is used to add an entry for the 10.1.10.1 into the Frame Relay map table via the use of DLCI 5.
DLCI 35 replaces the MAC address in the ARP table for entry 10.1.10.1.
A Layer 2 address is statically mapped to a Layer 3 address.
Router BRT uses DLCI 35 to forward data to 10.1.10.1.

It creates separate pathways for different VLANs.
It creates two tunnels, one for user traffic and one for management traffic such as CDP and SNMP.
It allows user traffic that is destined for the corporate network to travel across the VPN tunnel, while traffic destined for the Internet travels through the local LAN of the VPN client.
It allows separate tunnels so that high priority traffic, such as voice and video, uses the higher bandwidth tunnel, while all other user traffic travels on the lower bandwidth tunnel.

The firewall router and ISP connection represent a single point of failure.
If one of the Layer 3 switches fails, the Cisco Call Manager will be unreachable.
A power supply failure of the server block switch will cause the entire IP telephony system to fail.
Using Layer 3 switches to interconnect the server block servers to the IP phones introduces too much delay.
The IP phones need to be redundantly connected to the switches to prevent single points of failure at the access layer.
