Chapter 1 Adjacency Table Configuration
When configuring adjacency table, go to these sections for information you are interested in:
l Displaying and Maintaining the Adjacency Table
& Note:
l Currently, the adjacency table feature is available only on the POS interface with PPP as the link layer protocol.
l Currently, the adjacency table feature only applies to hardware forwarding, instead of software forwarding.
l The adjacency table feature does not apply to Ethernet, which uses ARP for storing and managing neighbor information.
1.1 Adjacency Table Overview
1.1.1 Introduction to Adjacency Table
An adjacency table manages the information on the neighbors that are both connected and active. An adjacency table maintains such information as neighbor network layer address (nexthop), route outgoing interface, link layer service type, and link layer address (PVC for ATM; unavailable for PPP).
The concept of neighbor is relevant to network layer. Node B may be an IP neighbor of node A, while node B may not be an IPX neighbor of node A. Also, a neighbor in the active state is in relation to network layer. Currently, the adjacency table feature only supports the neighbor concept in relation to IP.
A device can be connected with its neighbors through multiple link layer protocols, such as PPP, ATM and FR (frame relay).
1.1.2 Terms
l Routing interface: Outgoing interface in a route entry.
l Physical interface: Such as serial interface, POS interface, and ATM interface.
l Logical interface: An abstract interface that does not correspond to any physical entity and is used for adjacency table implementation, for example, Virtual-Ethernet interface, and Virtual-Template interface.
