Command Modes INTERFACE Command History Version 8.3.3.1 Version 7.6.1.0 Version 7.5.1.0 pre-Version 6.1.1.1 Introduced on S60 Introduced on S-Series Introduced on C-Series Introduced on E-Series Usage Information To change to a different key on the interface, enable the new key while the old key is still enabled. The FTOS will send two packets: the first packet authenticated with the old key, and the second packet authenticated with the new key. This process ensures that the neighbors learn the new key and communication is not disrupted by keeping the old key enabled. After the reply is received and the new key is authenticated, you must delete the old key. Dell Force10 recommends keeping only one key per interface. Note: The MD5 secret is stored as plain text in the configuration file with service password encryption. Open Shortest Path First (OSPFv2 and OSPFv3) | 715
