7.8 NHRP Configuration
NOTE: NHRP Configuration requires a feature license and hardware version 2.0. Go to System Settings → Feature Licenses to enable this
feature.
Next Hop Resolution Protocol is a protocol used to discover addresses of clients on Non-Broadcast Multiple Access
(NBMA) networks. It is used to create next-generation VPN technologies that allow shortcutting between spokes. With
NHRP, systems attached to an NBMA network dynamically learn the NBMA address of the other systems that are part of
that network, allowing these systems to directly communicate without requiring an intermediate hop.
The NHRP Supported Interfaces table displays the following fields for each configured NHRP interface.
• Name: Name of the GRE tunnel that
NHRP will use.
• Protocol Address/Prefix: GRE tunnel
endpoint mapping that NHRP
associates with the NBMA server.
• NBMA Address: NBMA server address the protocol address/prefix is associated with.
• Flags:
o SD: Shortcut-Destination
o N: Non-Caching
o S: Shortcut
o R: Redirect
