Bridging Network Protocol
To configure bridging as the network protocol and RFC 1483 or RFC 1490 as the link
protocol, you need the following information:
VPI and VCI numbers (for RFC 1483)
The VPI and VCI numbers apply to ATM routers only. Your router may have been
preconfigured with VPI/VCI numbers. If not, get these numbers from your Network
Service Provider.
If you are connecting to multiple remote sites, get additional VPI and VCI numbers
from your Network Service Provider. These numbers identify the remote destination
and must be unique for each remote.
For a Frame Relay router, its DLCI number
The DLCI (Data Link Connection Identifier) number applies to Frame Relay routers
only. Get your DLCI from your service provider.
DNS Internet Account Information (optional)
The Domain Name Service (DNS) maps host names to IP addresses. DNS is
performed by Domain Name Servers. The router can get DNS information
automatically. Or, you can choose to configure DNS manually. Consult with your
Network Service Provider to determine if you need to enter the following information:
• DNS server address
• DNS second server address
• DNS domain name
MAC Encapsulated Routing
MAC Encapsulated Routing (MER) allows IP packets to be carried as bridged frames
(bridged format). The link protocol RFC 1483 with MER (referred to as RFC
1483MER) is a multiprotocol encapsulation method over ATM used by ATM routers.
RFC 1490 with MER (referred to as RFC 1490MER) is a multiprotocol encapsulation
method over Frame Relay used by Frame-Relay routers.
RFC 1483MER and RFC 1490MER combined with the IP, IPX, or Bridging network
protocols share the same configuration characteristics, except for the connection
identifiers: VPI/VCI numbers are used for RFC 1483MER and a DLCI number is used
for RFC 1490.
IP Routing Network Protocol
VPI and VCI numbers (for RFC 1483MER)
The VPI and VCI numbers apply to ATM routers only. Your router may have been
preconfigured with VPI/VCI numbers. If not, get these numbers from your Network
Service Provider and then configure them.
