Modify OSPF jurisdiction distance

The jurisdictional distance is the source of route selection information, for example, the trust rate of a single vro or a group of vrouters. It is represented by a number, and the jurisdictional distance is 0 ~ An integer between 255. Generally, the higher the value, the lower the credibility rate. If the distance is 255, the routing information source is not reliable and should be ignored.
OSPF uses three different jurisdictions: Intra-domain, inter-domain, and external. The routes in one region are intra-domain; the routes to the other region are inter-domain; the routes from the other route selection domain obtained through re-allocation are called external routes. The default distance of each type of route is 110.

To modify any OSPF distance value, run the following command in the vro configuration mode:

Command	Function
Distance ospf {[intra-area dist1] [inter-area dist2] [external dist3]}	Modify the OSPF distance value.
