Parameter OSPF Specification
When routers • Routers send LSAs:
send LSAs and
– not more than every 5 seconds
other messages
– not less than every 4 minutes
– when topology changes
• Routers send:
– an ACK when they receive a LSA
– a hello every 10 seconds
To configure OSPF on an internal router, you must:
set the router ID
define each OSPF network
When you define an OSPF network, you:
enable the interface on that network to send and receive LSAs
enable all OSPF interfaces on the router to advertise that network
place the network within an area
If the router is in a stub area, you must also define the area as a stub area.
To configure OSPF on an ABR, you must:
set the router ID
define the OSPF networks in each area
define stub areas and total stub areas
configure route summarization
To configure OSPF on an ASBR, you must:
configure the EGP (see "Configuring RIP" on page 15-12 or "Configuring
BGP" on page 15-67)
set the router ID
define the OSPF networks
generate a default route or route summaries for external routes
For each router, you can also:
fine tune cost calculations
redistribute routes discovered by other protocols (including external
routes for ASBRs)
raise a router's priority for being elected DR
alter intervals for OSPF messages sent on an interface
alter SPF calculation intervals
enable authentication
