Number of OSPF processes

Hi!

I would like to know are there any limitations in number of OSPF processes in IOS-XR, especially on ASR9010 platform?

  Active Packages:
    disk0:asr9k-mini-px-4.3.4
    disk0:asr9k-fpd-px-4.3.4
    disk0:asr9k-doc-px-4.3.4
    disk0:asr9k-mpls-px-4.3.4
    disk0:asr9k-services-px-4.3.4
    disk0:asr9k-k9sec-px-4.3.4
    disk0:asr9k-px-4.3.4.sp2-1.0.0
    disk0:asr9k-px-4.3.4.CSCuh93866-1.0.0
    disk0:asr9k-px-4.3.4.CSCui28202-1.0.0
    disk0:asr9k-px-4.3.4.CSCuo16209-1.0.0
    disk0:asr9k-px-4.3.4.CSCuo17130-1.0.0
    disk0:asr9k-px-4.3.4.CSCuo53524-1.0.0
    disk0:asr9k-px-4.3.4.CSCuo84606-1.0.0
    disk0:asr9k-px-4.3.4.CSCun32418-1.0.0
    disk0:asr9k-px-4.3.4.CSCum44940-1.0.0
    disk0:asr9k-px-4.3.4.CSCuo78473-1.0.0
    disk0:asr9k-px-4.3.4.CSCuo68417-1.0.0
 

Now, configuring 11th OSPF process, system throws following error:

router ospf test
!!% 'CfgMgr' detected the 'fatal' condition 'This configuration has not been verified and can not be accepted by the system.'
 

Thanx in advance!

Have found some info.

the number of OSPF processes is finite (max 10, but best to not exceed 4), so 
please configure the VRF PE-CE routing instances within the same process (which 
is different from IOS where you would set up distinct "router ospf ..." per 
vrf). A common deployment is to use two processes: One as the core IGP, and one 
for all VRFs.

Spot on! Yep 10 is the max

Spot on!

 

Yep 10 is the max for v2 and v3, but 4 is the max recommended.

This is different from IOS where we use a separate instance per VRF, instead use multiple VRF configurations under the same OSPF process.
