NBMA IP Interfaces
Overview
Non-broadcast multi-access (NBMA) functionality was added to RIP and
OSPF routing protocols on the Avaya Multiservice switch software. Support
for this functionality was added to enable route exchange over nonbridged
connections (routed PVCs).
This feature makes it possible for the switch to exchange routing
information over nonbridged connections (routed virtual switch ports).
NBMA functionality has been added to the RIP and OSPF routing protocols
in the switch software and has been tested with other routers.
Operation of OSPF over NBMA is almost identical to operation of OSPF
over broadcast LANs. Flooding uses the designated router, and both subnets
are represented identically within the OSPF link-state database by network-
LSAs. The only real difference between broadcast subnets and NBMA
subnets is in the discovery of neighboring routers. On broadcast networks, a
router can discover its neighbors dynamically by sending multicast Hello
packets; on NBMA networks, a router's neighbors may have to be
configured.This feature makes it possible for you to set up an IP interface as
NBMA. Each IP routing protocol may then have IP addresses that are
designated as NBMA neighbors.
