Processing Snmp And Sending Snmp Traps (Ospfv2, Ipv4 Only); Rfc-2328 Compliant Ospf Flooding - Dell Force10 Z9000 Configuration Manual

• The E-Series supports up to 28 OSPFv2 processes.
• The C-Series supports up to 6 OSPFv2 processes.
• The S50 and S25 support up to 4 OSPFv2 processes.
• The S55 and S60 support up to 16 OSPFv2 processes.
• The S4810 and Z9000 support up to 32 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
function.
Processing SNMP and Sending SNMP Traps (OSPFv2, IPv4
only)
Though there are may be several OSPFv2 processes, only one process can process SNMP requests and
send SNMP traps. The
responsible for SNMP management. If the
created manages the SNMP processes and traps.

RFC-2328 Compliant OSPF Flooding

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.) When 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.
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
similar to the following:
| Open Shortest Path First (OSPFv2 and OSPFv3)
630
command identifies one of the OSPVFv2 processes as the process
mib-binding

command is not specified, the first OSPFv2 process
