1. If ACL, use numerical ACL as possible.
2. If you want to prevent advertising update, use passive-interface as possible.
3. Do map FR interface to ping itself even if you are instructed with "you do not need".
4. DO NOT use "isdn test" command that has no assurance the L3 connectivity and waste my half hour.
5. DO config ISDN part at the last step or the 4-point section will reduce your 10 points or more.
Hi, Thomwin:
Yes, the class B address will cause RIP advertise on all the interface, so you need "passive-interface" to restrict the advertising.
