a3RipIpPoisonCtl
Module: A3COM-RIP-IPEXTNS-R4-MIB
OID (symbolic): A3COM-RIP-IPEXTNS-R4-MIB::a3RipIpPoisonCtl
OID (numeric): 1.3.6.1.4.1.43.2.8.2.1.5
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This parameter determines how split horizon is performed. To achieve split horizon, RIP-IP refrains from advertising a route to a port if the gateway for this route can be reached on the same port. If poison (1) is selected, RIP-IP advertises the route but it uses infinity (16) for the metric. If noPoison (2) is selected, the route is not advertised.
What is a3RipIpPoisonCtl?
This OID configures split-horizon loop prevention: 'poison' advertises routes with infinite metric, 'noPoison' suppresses them entirely. Poison is gentler on convergence but uses more bandwidth; engineers choose based on network stability needs. Poison (1) sends the route with cost 16, noPoison (2) omits it.
Examples
Walk all instances (SNMPv2c):
