In this article I will configure, debug and shows the process of RIPv2 authentication.
- Default route origination not working reliably.
- Automatic summarization turned on causes major networks to be propagated throughout the RIP domain with a metric of 1.
- Using RIPv2 on NBMA hub-and-spoke topology causes the hub router to rewrite the next hop field in the RIPv2 update to the IP address of the spoke router advertising the originalupdate, thereby creating reachability issues
Recovering from a Lost or Forgotten Password
The default configuration for the switch allows an end user with physical access to the switch to recover from a lost password by interrupting the boot process during power-on and by entering a new password. These recovery procedures require that you have physical access to the switch.
