The Z9000 supports up to 16 OSPFv2 processes.

Each OSPFv2 process has a unique process ID and must have an associated Router ID. There must be an

equal number of interfaces must be in Layer-3 mode for the number of processes created. For example, if 5

OSPFv2 processes are created on a system, there must be at least 5 interfaces assigned in Layer-3 mode.

Each OSPFv2 process is independent. If one process loses adjacency, the other processes continue to

Processing SNMP and Sending SNMP Traps

Though there are may be several OSPFv2 processes, only one process can process SNMP requests and

send SNMP traps. The

command identifies one of the OSPVFv2 processes as the process

responsible for SNMP management. If the

command is not specified, the first OSPFv2 process

created manages the SNMP processes and traps.

In OSPF, flooding is the most resource-consuming task. The flooding algorithm described in RFC 2328

requires that OSPF flood LSAs on all interfaces, as governed by LSA's flooding scope. (Refer to Section

13 of the RFC.) hen multiple direct links connect two routers, the RFC 2328 flooding algorithm generates

significant redundant information across all links.

By default, FTOS implements an enhanced flooding procedure which dynamically and intelligently detects

when to optimize flooding. Wherever possible, the OSPF task attempts to reduce flooding overhead by

selectively flooding on a subset of the interfaces between two routers.

in ROUTER OSPF

If RFC 2328 flooding behavior is required, enable it by using the command

mode. When enabled, this command configures FTOS to flood LSAs on all interfaces.

Confirm RFC 2328 flooding behavior by using the command
