Configuring the Administrative Distance for OSPF Routes

If several routes coming from different protocols are presented to the Route Table Manager (RTM), the protocol with the lowest administrative distance will be chosen for route installation. The S- K- and 7100-Series platform supports connected, static, OSPF, and RIP routes.

The table below displays the default distance for these routing protocols.

Route Source Default Distance
Connected 0
Static 1
BGP (S-, 7100-Series) 20 - Routes external to the AS

200 - Routes internal to the AS

OSPF 110
RIP 120

Use the distance ospf command in OSPFv3 router configuration command mode to change the administrative distance assigned to the OSPFv3 protocol. This command provides for the configuration of separate values for OSPFv3 external and intra-area routes.
