Configuring OSPF Routing
Configuring OSPF routing in the MAX
MAX 6000/3000 Network Configuration Guide 8-15
A Type-1 external metric is expressed in the same units as the link state metric (the same
units as interface cost). Type-1 is the default.
A Type-2 external metric is considered larger than any link-state path. Use of Type- 2
external metrics assumes that routing outside the AS is the major cost of routing a packet,
and eliminates the need for conversion of external costs to internal link-state metrics.
5 Set the ASE-tag parameter to specify an ASE tag for this route.
The ASE tag is a hexadecimal number that shows up in management utilities and flags this
route as external. It can also be used by border routers to filter this record. For example:
ASE-tag=cfff8000
6 Exit the profile and, at the exit prompt, select the exit and accept option.
Note: The remote Pipeline unit must have a comparable Connection profile to connect to the
MAX.
Configuring the MAX as an NSSA internal router
Because the MAX cannot be an Area Border Router, when you configure OSPF on the MAX
keep in mind that:
• The area type must be the same on all MAX interfaces running OSPF.
• The area ID (configured in the Area parameter) must be the same on all MAX interfaces
running OSPF.
To configure the MAX as an NSSA internal router:
1 Set Ethernet > Mod Config > OSPF options > AreaType to NSSA.
2 Exit the profile and, at the exit prompt, select the
exit and accept option.
3 Select Ethernet > Static Rtes > any profile and configure a static route to the destination
outside the NSSA. For example:
Ethernet
Static Rtes
90-401 Static Rtes profile 1

Active=Yes
Dest=20.20.20.20
Gateway=10.10.10.10

NSSA-ASE7=Advertise
Note: Set the NSSA-ASE7 parameter to Advertise, or to DoNotAdvertise, to specify
whether you want to advertise this route outside the NSSA. The settings for the remaining
parameters depend on your environment.
