Configuring BayStack Remote Access
1-6 117341-A Rev. A
The BayStack router sends the BootP request through all serial ports at
approximately the same time, using the following protocols:
Bay Networks Standard Point-to-Point Protocol (PPP) using HDLC
encapsulation
Frame Relay Annex D
Frame Relay Local Management Interface (LMI)
Frame Relay Annex A
If the BayStack router does not receive a response to the first BootP request, it
issues a second request.
If the BayStack router does not receive a response in approximately four
minutes, it boots the image and configuration files in its local file system, as
described in “Local Boot Pr
ocess” on page 1-12.
3. The first interface on the upstream router to receive the BootP request
responds.
4. The upstream router obtains the IP address of the BayStack router’s serial
interface. The protocol configuration of the upstream router determines
whether it calculates or requests the IP address, as follows:
-- A Frame Relay PVC in direct access mode or a Bay Networks Standard
PPP interface calculates the IP address by adding 1 to the IP address of
the interface that received the request.
For example, in Figure 1-1, the upstream router’s interface address is
192.32.1.1. This means that the upstream router calculates 192.32.1.2 as
the BayStack router’s IP address.
Note: The upstream router must have a circuit running Bay Networks
Standard PPP using HDLC or a Frame Relay permanent virtual circuit (PVC).
Note: If the IP address plus 1 equals a broadcast address, the upstream router
calculates the IP address by subtracting 1. For example, if the IP address of the
upstream router’s interface is 7.255.255.254, the IP address of the BayStack
router is 7.255.255.253.
