A device at a customer site that connects to the Dial VPN network via a WAN
link. With Dial VPN, the customer site connects to a Dial VPN network by
means of a frame relay network.
Stripping protocol-specific information from a data packet.
Bay Networks Virtual Dial Private Network Services (Dial VPN) provides
secure dial access services for corporate telecommuters, mobile professionals,
and users in remote branch offices.
Data Link Connection Identifier is a number that uniquely identifies a virtual
circuit at each frame relay interface.
Domain name information server.
Adding protocol-specific information to a data packet.
Bay Networks proprietary Expedited Remote Procedure Call Daemon.
• A device that converts the protocols and conventions of one network to
those of another, for instance, between an IP network and a frame relay
network.
• A device that forwards traffic between networks, based on network layer
information and routing tables, now known as a router.
A method of encapsulating arbitrary network layer protocol information over
another arbitrary network layer protocol. The encapsulation allows the first
network layer protocol data to be tunneled transparently across the second
network layer protocol environment. GRE is documented in RFC 1701 and
RFC 1702.
A message that the ACP server sends to the network access server to verify
that the remote user is an authenticated user. The Grant message contains the
following information, which is stored in the TMS database:
• Remote node's domain name
• Domain name information server (DNIS)
• The home agent's IP address that resides on the gateway
• Maximum number of users
• Type of connection between the gateway and the CPE router on the home
network
• The primary and secondary RADIUS server's IP address
• Authentication protocol information
The network access server uses this information to contact the RADIUS server
on the home network.
