The newest setup order is significantly less than router ospf , and also the second sentence structure:
Inside Ios several.1(6) and better, the latest throw away route is instantly from default. When the unconditionally you ought not risk use this dispose of channel, you could potentially configure another commands less than router ospf :
- Either [no] discard-route inner
- Or [no] discard-station external
Note regarding summation target metric formula: RFC 1583 requisite figuring the brand new metric to own summary pathways mainly based towards lowest metric of your own part routes readily available.
RFC 2178 (today obsoleted from the RFC 2328) altered the desired way for figuring metrics for summary paths therefore the newest component of the latest conclusion towards restrict (or premier) cost manage determine the expense of this new conclusion.
Prior to Apple’s ios several.0, Cisco are compliant on the then-current RFC 1583. Since Ios several.0, Cisco changed the new behavior off OSPF getting compliant with the new practical, RFC 2328. This example created the chances of sub-max routing if most of the ABRs into the an area were maybe not upgraded on brand new code meanwhile. (περισσότερα…)
