Chapter 38 Configuring IP Unicast Routing
Configuring OSPF
OSPF Nonstop Forwarding
The switch stack supports two levels of nonstop forwarding (NSF):
• OSPF NSF Awareness, page 38-28
• OSPF NSF Capability, page 38-28
Distance OSPF dist1 (all routes within an area): 110.
dist2 (all routes from one area to another): 110.
and dist3 (routes from other routing domains): 110.
OSPF database filter Disabled. All outgoing link-state advertisements (LSAs) are
flooded to the interface.
IP OSPF name lookup Disabled.
Log adjacency changes Enabled.
Neighbor None specified.
Neighbor database filter Disabled. All outgoing LSAs are flooded to the neighbor.
Network area Disabled.
NSF

. Allows Layer 3 switches to continue forwarding
packets from a neighboring NSF-capable router during hardware
or software changes.
NSF capability Disabled.
Note The Catalyst 3750-E switch stack supports OSPF
NSF-capable routing for IPv4.
Router ID No OSPF routing process defined.
Summary address Disabled.
Timers LSA group pacing 240 seconds.
Timers shortest path first (spf) spf delay: 5 seconds.
spf-holdtime: 10 seconds.
Virtual link No area ID or router ID defined.
Hello interval: 10 seconds.
Retransmit interval: 5 seconds.
Transmit delay: 1 second.
Dead interval: 40 seconds.
Authentication key: no key predefined.
Message-digest key (MD5): no key predefined.
1. NSF = Nonstop forwarding
2. OSPF NSF awareness is enabled for IPv4 on Catalyst 3750-E and 3560-E switches running the IP services feature set.
