In-depth analysis of Route redistribution (3)

Route redistribution key aspect 6

The route information redistribution procedure between RIP v2 and OSPF is as follows:

In RIP v2, no auto-summary must be written; otherwise, unnecessary routing information is generated.

In this example, the passive-interface s2 command does not advertise rip information to the ospf area from the speed port.

The Passive-interface command cannot be used in VPN or IGRP. Otherwise, the neighbor cannot be created. Shows the redistribution command:

Because no route information of each vro is summarized, a large number of Route entries are generated on each vro. to reduce these route entries, the route information is summarized on the vro, shown as follows:

Passive-interface default makes all rip information of 10.0.0.0 unacceptable and cannot be sent. When combined with the preceding command, no pasive-interface s1 allows rip information to be transmitted from s1, A little negative.
