Cisco “Exit Interface Failed Test” using SDM or CCP

When doing Cisco connectivity tests, you can stumble upon vague error messages that leave you feeling a little inadequate.

I encountered one recently when reconfiguring my Dialer0 outside interface for a DSL connection, it ended up being so simple so I thought I’d share it with the world.

I was using the Cisco Configuration Professional (CCP) software but I believe the SDM software can report the same thing.

Exit Interface Failed Test

Log into router

  1. enable
  2. configure terminal
  3. ip routing
  4. exit

Re-run the test, it should have fixed it.
