Assigning OSPFv3 Process ID and Router ID to a VRF
To assign, disable, or reset OSPFv3 on a non-default VRF, use the following commands.
• Enable the OSPFv3 process on a non-default VRF and enter OSPFv3 mode.
CONFIGURATION mode
ipv6 router ospf {process ID} vrf {vrf-name}
The process ID range is from 0 to 65535.
• Assign the router ID for this OSPFv3 process.
CONF-IPV6-ROUTER-OSPF mode
router-id {number}
– number: the IPv4 address.
The format is A.B.C.D.
NOTE: Enter the router-id for an OSPFv3 router as an IPv4 IP address.
• Disable OSPF.
CONFIGURATION mode
no ipv6 router ospf process-id vrf {vrf-name}
• Reset the OSPFv3 process.
EXEC Privilege mode
clear ipv6 ospf [vrf vrf-name] process
Configuring Stub Areas
OSPF supports different types of LSAs to help reduce the amount of router processing within the areas.
Type 5 LSAs are not flooded into stub areas; the ABR advertises a default route into the stub area to which
it is attached. Stub area routers use the default route to reach external destinations.
To ensure connectivity in your OSPFv2 network, never configure the backbone area as a stub area.
To configure a stub area, use the following commands.
1. Review all areas after they were configured to determine which areas are NOT receiving type 5 LSAs.
EXEC Privilege mode
show ip ospf process-id [vrf vrf name] database database-summary
2. Enter CONFIGURATION mode.
EXEC Privilege mode
configure
3. Enter ROUTER OSPF mode.
