6.7.4 Configuring OSPFv3 to Import External Routes

Importing the routes discovered by other routing protocols can enrich OSPFv3 routing
information.
Context
Because OSPFv3 is a link state-based routing protocol and cannot directly filter the advertised
LSAs, OSPFv3 must filter the routes when importing them. Then, only the routes that pass the
filtering can be advertised.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
ospfv3 [ process-id ]
The OSPFv3 view is displayed.
Step 3 Run:
default { cost cost | tag tag | type type }
The default cost of the imported route is set.
Step 4 Run:
import-route protocol [ process-id ] [ { cost cost | inherit-cost } | type type |
tag tag
External routes are imported.
Step 5 (Optional) Run:
import-route bgp [ permit-ibgp ] [ { cost cost | inherit-cost } | type type | tag
tag | route-policy route-policy-name ]
IBGP routes are imported in OSPFv3 process.
Step 6 (Optional) Run:
default-route-advertise [ always | cost cost | type type | tag tag | route-policy
route-policy-name [ match-any ] ]
