nwAtProtoIfType

Module: CTRON-AppleTalk-ROUTER-MIB

OID (symbolic): CTRON-AppleTalk-ROUTER-MIB::nwAtProtoIfType

OID (numeric): 1.3.6.1.4.1.52.4.2.2.2.3.4.2.4.1.1.2.1.1.1.14

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Indicates whether the directly connected network segment does or does not support broadcast media access. If broadcast media access is supported, AppleTalk routing protocol advertisements are sent out one broadcast packet per port. If broadcast media is not supported, AppleTalk routing protocol advertisements are sent to each neighbor.

What is nwAtProtoIfType?

This read-write INTEGER (other/bma/nbma) indicates whether the network segment attached to a router port supports broadcast media access; the description notes that on broadcast media, routing advertisements go out as one broadcast per port, while on non-broadcast media they're sent individually to each neighbor. An administrator sets it to match the actual media type so route advertisements are delivered correctly. Setting nwAtProtoIfType to nbma(3) on a port connected to a point-to-point or non-broadcast WAN link ensures the router sends separate route advertisements to each neighbor instead of relying on a broadcast that medium can't deliver.
