CCNP - SWITCH - Inter-vlan Routing Notes

- Router interfaces on a Router-on-a-stick setup are configured as L3 subinterfaces

- Reasons you wouldn't need to implement an SVI;
i) Provide failover for a failed primary SVI
ii) Provide connectivity to an external router for inter-vlan routing

- The cmd 'Autostate Exclude' could be implemented on a port that is used for monitoring and is connected to an IDS

- A Glean adjacency is when a MLS connects directly to several hosts and the FIB table maintains a prefix for the subnet rather than individual host prefixes

- If you get 'incomplete' or 'drop' adjacencies check the switch hasn't been configured with unsupported software features.
