Network Topology Example Figure 1 shows many of the connectivity options provided by the BN function. Ingeneral, you can get from any network to any other network except that NetF canonly reach network NetE and NetE is the only network that can reach NetF.

v Both ends of an inter-network link must be BNs, unless one of the networks is aperipheral network. In this case, the peripheral network may use a conventionalnon-BN network node to connect to the BN in the adjoining network.

Chapter 11. Using NHRP This chapter describes how to use: v Next Hop Resolution Protocol (NHRP) as specified in Internet Draft Version 13, which has been submitted for RFC status.

So, for “one-hop” routing this operation happens once duringtransfer of a packet from its source to its destination. v The IBM implementation can operate in networks where some routers do notsupport NHRP. If the next-hop router is not capable of providing NHRP support,shortcut VCs can b...

NHRP in a Classic IP Environment with non-NHRP Device This example shows how NHRP can be used between two 1577 devices. when oneof them does not support NHRP. Here, Device2 provides the NHRP client with theATM address of the non-NHRP device and the client can establish a shortcut fortraffic to the n...

NHRP in a Pure LAN Emulation Environment In the LAN emulation case, routers use the IBM extensions to provide NBMAinformation for devices on their ELANs. When Device1 receives traffic from host Adestined to host B, it originates a Next Hop Resolution Request and sends it on therouted path. Device2 r...

This example also illustrates that the ELAN environment can be token-ring orEthernet or any mixture of LAN types. NHRP in a Mixed Classical IP and ELAN Environment The NHRP function in the router can operate with both Classic IP and ELANinterfaces in the same network. In this example, the NHRP clien...

NHRP to an Egress Router The source and/or destination stations of protocol traffic do not have to belong tosubnets served by NHRP participants. They may access the ATM network viarouters that communicate with the NHRP devices. In this case, the 2210 providesshortcuts through the ATM network to elim...

NHRP Implementation NHRP interacts with the router function in the router. When the router function inthe router is forwarding packets along the routed path and NHRP successfullyobtains a shortcut VC, NHRP will update the router function to send the packetdirectly over the shortcut VC. NHRP updates ...

By default, the LSI will use the MAC address burned into the associated ATMadapter as the source MAC address of frames transmitted over the LANE shortcutVCCs. It is possible, though unlikely, that this could confuse some end-stationprotocol stack implementations, since the MAC address will not match...

Extensions The NHRP protocol includes Extensions. Extensions are appended to NHRPpackets. Extensions are used to request additional functions from the NHRPparticipants. The use of the extensions parameter lets you determine if the routersends certain extensions: v path information extensions v IBM v...
