Configuring Authentication Key Updates (NSM Procedure)

You can configure authentication key updates for the Border Gateway Protocol (BGP) and Label Distribution Protocol (LDP) routing protocols. Authentication key updates can occur without interrupting routing and signaling protocols such as Open Shortest Path First (OSPF), and Resource Reservation Setup Protocol (RSVP) when configured using this option.

  1. In the NSM navigation tree, select Device Manager > Devices.
  2. Click the Device Tree tab, and then double-click the device to select it.
  3. Click the Configuration tab. In the configuration tree, expand Security.
  4. Select Authentication Key Chains.
  5. Add or modify settings as specified in Table 1.
  6. Click one:
    • OK—Saves the changes.
    • Cancel—Cancels the modifications.
