Configuring gated
Configuring the OSPF Protocol
2 routes should be routes from external gateway protocols with
metrics that are not comparable to OSPF metrics. When OSPF is
selecting a route, OSPF will ignore a type 2 route’s metric and use
only the OSPF internal cost to the AS border router.
Default: 1
• exportlimit specifies the rate that ASE routes are imported into
the gated routing table for each exportinterval (see below).
Default: 100 (ASE routes)
Range: 0 - 65535
• exportinterval specifies the interval, in seconds, between ASE
exports into OSPF.
Default: 1 (second)
Range: 0 - 2147483647
Sample OSPF Configuration
Figure 8-13 shows an example of two areas. Area 1 is a non-stub area,
while area 2 is configured as a stub area. Node B is an area border router
between the two areas.
