# Internal Addresses

  In an 802.5 source route bridging environment, the frame relay WAN looks like a Token Ring network to the frame relay access device and other RFC 1490-compliant devices.
  To make the frame relay network appear as if it were a giant ring, the unit serves as a frame relay-to-Token Ring bridge. This makes it necessary for the unit to have a logical internal ring.

Primary Internal Values

  These parameters must be configured for all frame relay access devices.

Internal / Global IP Management Address

  When RIP-2 is introduced, each branch can be assigned a unique host internal IP address. This address is broadcast as a host address instead of allocation another subnet as required in RIP-1.

Auxiliary Internal Rings (FRADs only)

  Tandem out-dial configurations require a unique MAC address for each SDLC ATM device. To support this requirement, up to nine MAC addresses may be identified.
  These values can also define internal routes that can be used by specific PUs. These values are required if you intend to implement session resiliency, or if you have a Tandem host supporting multiple PUs with a common destination. Since Tandem cannot support multiple sessions to the same destination address, each PU configured on the unit must use a unique internal MAC address for the same destination.
  These values are generally configured on the destination device.
  Downstream PUs can either be SDLC- or LAN-attached.
