Default Routing Task:
In what appeared to me as a possible solution to this task, on R6 I made interface gig1.146 a passive interface, I then configured "default-information originate on-passive"
Per the command reference: default-information originate "on-passive" option sends default routes only on RIP passive interfaces".
Initially it appeared to be working as advertised until I realized R7 was also getting the default directly from R6. The R6 interface facing R7 is Not configured as a passive-interface.
Is anyone familiar with how the "on-passive" option really work?
