Enabling Multi-Process OSPF
Multi-Process OSPF allows multiple OSPFv2 processes on a single router.
Follow the same steps as above, when configuring a single OSPF process. Repeat them as often as
necessary for the desired number of processes. Once the process is created, all other configurations apply
as usual,
Return to CONFIGURATION mode to enable the OSPF process. The OSPF Process ID is the identifying
number assigned to the OSPF process, and the Router ID is the IP address associated with the OSPF
process. .
Once the OSPF process and the VRF are tied together, the OSPF Process ID cannot be used again in the
system.
If you try to enable more OSPF processes than available Layer 3 interface you will see the following
message.
