Local Routes Behavior
PAN-OS specific behavior for the openconfig-local-routing
model.
The OpenConfig model for Static Routes
differs from the model used in PAN-OS:
- In PAN-OS static routes are organized in a flat list with
a single next-hop member per route. If multiple next hops are needed
for a given destination (prefix) then you must create multiple static
routes.
- In OpenConfig static routes are organized in a hierarchy containing
a list of next-hops members per each destination.
- PAN-OS requires each static route to have its own unique name
while in OpenConfig the static route key is the destination.
- The OpenConfig configuration only supports next-hop type IP
addresses.
- Local-aggregates are supported only if created with OpenConfig.
When rendering an existing PAN-OS configuration into OpenConfig
some values like the next-hop index are synthesized using low collision
hash functions. Static routes configured from the gNMI client contain
metadata like the next-hop index must be stored somewhere in order
to achieve consistent future responses and a unique name must be
synthesized for each route in order for PAN-OS to accept the routes.
For this reason, unique route name is automatically generated by
using a fixed-length Base64 prefix encoding the metadata plus an
optional route description.
